Serbian Puzzle Association announces
The Third Serbian Open Championship in Optimizers
The
third Serbian Open
Championship in solving optimizer puzzles, organized by Serbian Puzzle
Association, will start on Monday, November 29th. The contest will last
two weeks. It consists of two rounds, seven days each.
There will be 12 optimizer problems in total, 6 per round. Each puzzle
has separate scoring system. The contestant (or contestants) with the
best solution receives 25 points, second best solution is worth 21
points, the third 18, the fourth 16, the fifth 14, the sixth 12, the
seventh 11, and so on. Seventeenth-ranked competitor gets 1 point.
In each round, competitor's score will be the sum of his four highest
results. Two lowest scores will not count. In other words, one can
score at most 100 points per round.
This means that the contestants do not have to submit all 6 answers,
they can skip one or two per round if they choose so. On the other
hand, it can be good tactical move to submit all 6. Although you can't
receive more points, your rivals might get less.
There are neither negative points for wrong answers, nor bonus points
for fastest solvers. It is advised to write answers very carefully
because errors will not be tolerated.
The winner becomes one who scores the most points. In case of the same
point total, the tiebreakers will be the following: more "25s", then
"21s", "18s", etc. If the tiebreaker records are still the same, then
they will officially share the first place.
There is no entrance fee or special application form. Anybody
interested can participate. The top ten puzzlers will receive awards
via email. The best Serbian competitor will get the trophy and become
national champion for the year 2010.
The authors of the puzzles are Nikola Živanović (8 puzzles) and Čedomir
Milanović (4 puzzles). Since there will be only two of his puzzles in
each round, Čedomir has the right to participate, but, of course, not
to
submit the answers for his own puzzles.
The file with the puzzles for the first round will be posted on this
website on Monday, November 29th, 10 A.M. Central European Time
(CET=GMT+01.00). The deadline for submitting the answers is Sunday,
December 5th, 10 P.M. The results of the first round will be posted on

The Second Serbian Open Championship in Optimizers
Tanasić wins, Tokunaga second with perfect score
Four
more competitors
joined in the second round to make total of 57 puzzlers from 19
countries. The winner of this year's competition and Serbian champion
became Zoran Tanasić from Belgrade, who made one best and three second
best solutions to edge the closest competition for just two points.
Tomaoki Tokunaga from Japan was brilliant in the second round making
perfect 100 score, but it was not enough for the victory. The third is
Milovan Kovačević from Novi Sad, Serbia with the same number of points
but weaker tiebraker record. Last year's winner Vlad Klyachin from
Moscow, Russia, finished fourth, followed by Čedomir Milanović from
Kikinda, Serbia who also made huge improvement in the second round. All
competitors but one scored at least one point in the competition. Three
competitors scored points in every puzzle in the second round.
A brief summary of the puzzles from the second round:
1. Knight Moves on Pentominoes:
Three puzzlers made the perfect 60 score, but the others also were
good, so all the contestants who sent the solution scored at least a
point, and those who were patient scored much more.
2. Year of Astronomy : A classical
crossword puzzle gave us the usual variety of beautiful solutions.
Čedomir Milanović was the best by some margin, with beautiful 3x3
square well placed inside the crossword.
3. Step by Step : This was the most
popular puzzle of the second round, and many contestants managed to
score over 600. Tomoki Tokunaga was the best by far, as he outscored
the second competitor by a greater margin than the second outscored the
tenth.
4. Archery: A very difficult puzzle, at
it turned to be the most unfortunate one. We are sorry for the puzzlers
who made a mistake on this puzzle, because they got 0 score. There was
simply no way to recover any score if a number showed the wrong number
of arrows. Tokunaga once again showed his skill and made another
impressive result.
5. Hit the Score : Probably the easiest
puzzle of the whole contest, 24 participants found the optimal
solution, and almost all who sent the solution scored at least a point
on this puzzle.
6. Mirror, Mirror, on the Wall :
Although it did not seem that this puzzle would produce a great variety
of solutions, it was quite the opposite. Many contestants used some
different techniques to increase the number of mirrors hit. Three of
them found 46 hits, but two best managed to distribute them more evenly
and got the top score. Interestingly, the two top solutions were almost
identical, only one had the queen's beam finish at a dwarf, other at
the edge of the grid.
Final Standings of all 57 participants:
1. Zoran Tanasić (Belgrade, Serbia) 177, 2. Tomaoki Tokunaga (Japan) 175, 3. Milovan Kovačević (Novi Sad, Serbia) 175, 4. Vlad Klyachin (Moscow, Russia) 169, 5.

The Second Serbian Open Championship in Optimizers
First round results
In
the first round of the
Second Serbian Open Championship in Optimizers there were 53
competitors from 18 countries. After the first round the leader is
Milovan Kovačević from Novi Sad, Serbia, with four points advantage
over Zoran Tanasić from Belgrade, Serbia. The last year's winner Vlad
Klyachin from Moscow, Russia, currently occupies the third place,
followed by two debutants, Rade Goljović from Baljevac, Serbia and
Stefan Gyürki from Salov, Slovakia. All competitors but one scored at
least one point in the first round. Four competitors scored points in
every puzzle.
A brief summary of the puzzles from the first round:
1. Puzzle Serbia: The example
given unfortunately turned out to be too good (or bad), so the
competitors (13 of them) who used it as a base of their solution got
the best result.
2. Geomathematics: All participants
(except Nikola Živanović, the author) submitted their answers for this
puzzle and 9 of them found the optimal solution. The right path was to
sacrifice some columns in order to increase the value of the key
letters. Those who chose S and N turned out to be winners. Worth
mentioning is the solution found by Petar Parlić. It was quite close to
the optimal one, even though he used only one word from the optimal
solution.
3. Retrospect Word Search: Although the
least number of puzzlers submitted their answers, this puzzle had the
greatest variety of the solutions. The key was to spot three-letter
overlaps and use them wisely while trying to maximize the number of
used (short) words. The best solution by Nikola Živanović, breaking the
400 points limit is a fantastic effort.
4. Triplets: This puzzle, together with
puzzle 2, had the highest number of solvers. Quite a few got the result
higher than 22000, and seven of them got over 22800. But, the best
three chose to sacrifice one "9" and increase other addends for even
better score. Last year's winner, Vlad Klyachin, got the final finesse
right and outscored the rivals by 1 sole point!
5. European Flags: Because the range of
possible scores for this puzzle was rather narrow, all competitors who
submitted their answer got on the scoresheet. Although the puzzle was
simple, there were a lot of combinations and the best combiners managed
to make all possible 19 rectangles, with only 2 isolated squares, for a
total of 17. Nenad Savić also got 17, but in a different way: 18
rectangles, 1 isolated square, and 1 L-shaped area.
6. In the Museum: All competitors who
sent the correct solution got on the scoresheet, the scores were close,
but the paths through the museum were very different. Jiri Hrdina
managed to make 83 without touching the path even once, and Gulcin
Sabanci scored only 53 but was the only one to visit all exhibits.
Defending champion, Vlad Klyachin, once again showed his skills and

Serbian Puzzle Association announces
The Second Serbian Open Championship in Optimizers
The
second Serbian Open
Championship in solving optimizer puzzles, organized by Serbian Puzzle
Association, will start on Monday, November 30th. The contest will last
two weeks. It consists of two rounds, seven days each.
There will be 12 optimizer problems in total, 6 per round. Each puzzle
has separate scoring system. The contestant (or contestants) with the
best solution receives 25 points, second best solution is worth 21
points, the third 18, the fourth 16, the fifth 14, the sixth 12, the
seventh 11, and so on. Seventeenth-ranked competitor gets 1 point.
In each round, competitor's score will be the sum of his four highest
results. Two lowest scores will not count. In other words, one can
score at most 100 points per round.
This means that the contestants do not have to submit all 6 answers,
they can skip one or two per round if they choose so. On the other
hand, it can be good tactical move to submit all 6. Although you can't
receive more points, your rivals might get less.
There are neither negative points for wrong answers, nor bonus points
for fastest solvers. It is advised to write answers very carefully
because errors will not be tolerated.
The winner becomes one who scores the most points. In case of the same
point total, the tiebreakers will be the following: more "25s", then
"21s", "18s", etc. If the tiebreaker records are still the same, then
they will officially share the first place.
There is no entrance fee or special application form. Anybody
interested can participate. The top ten puzzlers will receive awards
via email. The best Serbian competitor will get the trophy and become
national champion for the year 2009.
The authors of the puzzles are Marko Obradović (8 puzzles) and Nikola
Živanović (4 puzzles). Since there will be only two of his puzzles in
each round, Nikola has the right to participate, but, of course, not to
submit the answers for his own puzzles.
The file with the puzzles for the first round will be posted on this
website on Monday, November 30th, 10 A.M. Central European Time
(CET=GMT+01.00). The deadline for submitting the answers is Sunday,
December 6th, 10 P.M. The results of the first round will be posted on
Friday, December 11th, the latest.
The second round begins on Monday, December 7th. The deadline for the
answers is Sunday, December 13th. The final results will be posted on
December 18th, the latest.
Good luck!

Vlad
Klyachin from Moscow,
Russia, is the winner of the First Serbian Open Championship in
Optimizers. In the second round, he solved six puzzles for a "perfect
ten" and surpassed Marko Obradović from Belgrade, Serbia. Finishing
second, as the best home competitor, Marko Obradović became the
champion of Serbia for the year 2008. Zoran Tanasić from Belgrade,
Serbia, took the third place.
As expected, the second round was as successful as the first. The
solutions were sent by 32 puzzlers from 13 countries, among them one
who did not take part in the first round.
In the second round the only contestant who scored points in all the
puzzles was Zoran Tanasić. The biggest leap was made by Zoran
Radisavljević from Novi Sad, who jumped up from 23rd to 11th place.
It is interesting that the additional tiebreaker rule was used to
decide 27th place. Simana Matković and Bjoern Roesel were tied with the
same score. As German puzzler did not send the answer for "Four in the
Row Around Serbia", the lady from Sombor won the tiebreaker.

17. World Puzzle Championship in Minsk
Serbia 8. in the world!
Belarussian capital Minsk
was the host of the 17. World Puzzle Championship from October 27th
till November 1st. At this contest of the world best puzzlers Serbia
took the eight place. The best result so far, 16. spot in Borovets in
2006, was overthrown by far.
This success was achived by Serbian team members: Nikola Živanović,
Dragan Tolomanoski, Marko Obradović, Čedomir Milanović and the team
captain Zoran Tanasić. In the individual category among 94 competitors,
Nikola was 21st, Dragan 45th, Marko 46th, and Čedomir 51th. The captain
Zoran Tanasić competed unofficially and his result would have been good
for 72nd place.
During the team sets Zoran
joined the group of three Indian puzzlers that could not form the full
team, so he wrote some history by being the leader of two teams at the
sam event! This year, the team sets brought the success to our squad.
The 10. set, especially, should be mentioned, as Serbia was, the only
team besides Czech republic, that solved the puzzles in time and got
bonus points. Even more interesting is that this set consisted of
arranging the pictures in order, the type of problem that on previous
championships was usually unsolvable.
On the top there was nothing new. Although this year there were 17
finalists, the first ranked after the regular sets, Ulrich Voigt from
Germany won the title ahead of Mehmet Murat Sevim from Turkey and Roger
Barkan from the USA. This was Voigt's sixth title, and since 2000. he
did not win only three competitions. In the team category, the best
were, as usual, the Americans, behind them the Japanese, and third came
Czecs after the outstanding performance on the team sets, although they
their team members did not reach the individual finals.
Final standings
(individually): 1. Ulrich Voigt, (Germany), 2. Mehmet Murat Sevim
(Turkey), 3. Roger Barkan (USA), 4. Peter Hudak (Slovakia), 5. Hideaki
Jo (Japan), ... , 21. Nikola Živanović, 45. Dragan Tolomanoski, 46.
Marko Obradović, 51. Čedomir Milanović.
Team standings: 1. USA, 2. Japan, 3. Czech republic, 4. Germany, 5.
Hungary, 6. France, 7. Slovakia, 8. Serbia, 9. Turkey, 10. Croatia, 11.
The Netherlands, 12. Russia, 13. Poland, 14. The Ukraine, 15. Canada,
16. Belarus, 17. Estonia, 18. Austria, 19. Bulgaria, 20. United
Kingdom, 21. Finland, 22. Italy. The complete results with detailed
scores by sets are available at the official
site of the championship.
The finals were very
interesting. In the first round there were five lowest ranked
finalists. In the next round competed two of them (the fastest solvers
of given three problems), as joined by next three from the list. In the
final round the top three competitors joined in. This method of
competing was interesting, but also very demanding for the finalists,
so nobody managed to pass two rounds, and the three "privileged"
competitors took the medals. The interesting was that in every round,
the contestant sitting on the chair next to the referee Ferhat
Calapuklu from Turkey managed to solve the puzzles first, so this chair
was, , named "pole position". In the final round, Ferhat was not the
referee, but his fellow countryman, Mehmet Murat Sevim from the "pole
position" took the silver medal.
During the championship, the regular assembly of the World Puzzle
Federation was held. Among the other things, the hosts for the
championships for the zear 2010 were decided. The Sudoku championship
were given to the USA unanimously so they will organize the fifth. WSC
in Philadelphia. For the host of the WPC 2010 there was a "battle"
between Serbia and Poland. After three rounds of voting, Poland won
12:10 (in the first two rounds the score was 8:8 and 9:9), so our
country lost again.The decision was also made that, starting from 2011,
the WSC and the WPC will be held together in the same city.
If
we take into account
that Belarus was given the organization, instead of Lithuania only
three months ago, we can say that everything was organized at the
highest level. The organizers, led by Vladimir Portugalov did excellent
job, especiallz regarding the puzzles. Everyone agrees that they have
never been better.
The excellent organization, good time, and, above all, the great
results in Minsk made us forget the problems the team had during our
travels, with Russian visas and plain tickets.
Some of our photos from Minsk can be seen in the gallery.
Serbian Puzzle Association would like to thank everyone who helped the team to go to Minsk and achive this great result.
The Fourth Serbian Puzzle Championship
Čedomir Milanović - new champion
The
champion of Serbia in logic puzzles solving for the year 2008. is
Čedomir Milanović from Kikinda. As a surprise winner, Čedomir took the
title ahead of former champion Dragan Tolomanoski form Sarajevo and
Marko Obradović from Belgrade, who lost the big point advantage he had
after first four sets. Those three puzzlers, together with the author
of the puzzles Nikola Živanović, will be the members of the Serbian
team in the next World Puzzle Championship, that will take place in
Minsk, from October, 27th till November 1st.
The championship was held at Military Veterans Association of Zvezdara
and there were fourteen competitors. After couple of hours of solving
four sets of problems, the best eight puzzlers went into the finals.
Marko Obradović had the great advantage ahead of Čedomir Milanović and
Dragan Stojanović from Belgrade. However, after he had made a
disastrous error in the puzzle that was worth the most points, he
almost lost his place in the Serbian team. Fortunately for him, Dragan
Stojanović also made a big error and ended up fourth. Čedomir Milanović
seized the opportunity and secured the title. Last year's champion
Dragan Tolomanoski was the best when it really mattered and with
brilliantly solved final set jumped up from the fifth to the second
place.
The standings of the
finalists (in the bracket are the points from first four sets):
1. Čedomir Milanović, Kikinda 453 (576)
2. Dragan Tolomanoski, Sarajevo 443.5 (487)

Great success of our competitors
Serbian puzzlers had
outstanding results on very prestigious contest on Turkish internet
site TurkZeka. Zoran Tanasić took fourth, and Čedomir Milanović sixth
place among 214 participants. Our third competitor, Milovan Kovačević
was 26. and had he not skipped four rounds, his result would have also
been in top ten. The first two were Japanese puzzlers Yoichi Enta and
Takanori Fujii, and the third was Meng-Hsuan Wu from Chinese Taipei. If
we compare the average scores achived by competitors from the same
country, then Serbia can be considered the most successful. Our three
competitors got in average 1128 points, the second is France (two
competitors) with 1115, the third is Czech republic (three competitors)
with 956, etc.
Zoran Tanasić and Helen Roberts from Great Britain were the only
contestants who solved 9 out of 10 given puzzles, while all the others
had less correctly solved problems.

16. World Puzzle Championship (Rio de Janeiro, 6-11th October 2007)
Good performance of Serbian puzzlers
The
most attractive
Brazilian city of Rio de Janeiro was the host of the 16. World Puzzle
Championship. Serbian competitors did well, even though due to the
expensive plane tickets, the team was not at the full strength. Facing
the very tough competition, notable results achived Nikola Živanović
(19th place among 95 competitors) and Dragan Tolomanoski (33th), while
Marko Obradović (83th) and Zoran Radisavljević (89th), besides their
enormous efforts ended the competition in the bottom part of the list.
Our best puzzler Nikola Živanović, twice finalist of World Sudoku
Championship, proved his class, and if he had not done the final set so
badly, he would have made the finals. The final set was poorly done by
all our team members, so Serbia took 17th place among 23 countries,
altough during the whole championship we were 14th. At the end, after
lots of incredible mistakes and blunders, we were only few points short
of 15th place, which would have been our best result ever.
Before the competition there was fear that the inexperienced organizers could make some erroneous or dubious problems. Unfortunately, the fear was justified, and after some accepted appeals there had been some major changes in the final ranking. Croatian team member Goran Vodopija was the unluckiest one, as he went to bed as a finalists and woke up the next morning as spectator of the final round. To add the insult to the injury, Hungarian Pal Madarassy, who had replaced him became the winner.
The results were arriving very slowly, and for the semifinal and final rounds the organizers did not give the copies of the problems to the audience. Luckily for the hosts, the charming sites of Rio made the competitors forget all the inconveniences.
In team category USA team
was the absolute winner, second place went to Japan, and the third was
Belgium. Germany, who was among the medalists throughout the whole
competition made the crucial mistake in the last set and got zero
points. This last set was very interesting. The participants had to
make the “incredible machine“ using office material (paper clips,
rulers, pencils, erasers, sharpeners, scotch tape) that would transport
the marble from point A to point B. The Germans, instead of making
something simple and receiving 900 points, tried some tape-pendulum
contraption which did not work so they descended from 2nd to 9th place!
The best machine was made by Japanese (24 seconds), while Serbian
“craftmen“ made the contraption that worked for about three seconds.
However, we showed them that we are basketball-nation, as only our
marble was thrown directly to the “ basket ” .
Final
results
(individual): 1. Pal Madarassy (Hungary), 2. Thomas Snyder (USA), 3.
Ulrich Voigt (Germany), 4. Okamoto Ko (Japan), 5. Taro Arimatsu

Third Serbian logic puzzle championship
Tolomanoski wins the trophy in style
The
third Serbian
championship in logic puzzles was held in Novi Sad on 12th of August.
There participated 14 competitors and the new champion became Dragan
Tolomanoski from Sarajevo, who collected 375 out of possible 480
points. The same score, but with weaker tiebreaker record, had the
"invincible" Nikola Živanović from Sombor. The second surprise was
Marko Obradović from Belgrade, who was in the lead after first set,
performed well in the other sets too, eventually winning the bronze
medal. The fourth member of Serbian team will be Jelena Đurić, who had
only half a point more than Dragan Stojanović. Among the newcomers, the
best was Čedomir Milanović, who would have had chances to win a medal,
if he had not done poorly the first set.
The
tournament official
and the puzzlemaker was Zoran Radisavljević, and Stjepan Varaždinac
from Orahovica and Adnan Spahić from Tuzla helped him. This was so far
the most unpredictable competition, which proves that we have many more
puzzle solvers for the future.
