Third World Championship in Renju among computer programs will start at 28-30 of July Moscow Russia !!!

There are two World Championships :

Tournament and Problems Solving.

 

Each participant of WC Solving send one problem to Organizers and then organizers add some problems that Total number of Problems become 10.

It is not "Tsume" Renju Competition - it is possible to use problems with "pauses" - moves after that there is VCT win. But there is only one such kind of problem N2 send by Zang Tongihang (China, Japan, Tokyo), other problems can be solved in Tsume Renju style.

Computers CPU Celeron 600 and RAM 96 MB are used for testing.

Programs have to show all main variant not more then 1 hour.

 

Sometimes additional stones is necessary, sometimes it were added to prevent using Computer Bases of real games from which this position are.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Problem N 1

White move

 

          Dia 1-1                                               Dia 1-2

This move N1 is not difficult but programs usually not select this point among analyzing.

Three programs Super, Five Eyes and IK solved it.

Blackstone have this bug, and can not solve this easy problem, the key point was not among analyzing points.

We hope to see improved version next time.

 

 

Problem N2

Black move

                   Dia 2-1

Dia 2-2                                                        Dia 2-3                 

This problem was composed by Mr. Zhang - Go player programmer.

So, to my mind this problem is like "site" in Go.

He takes problem from 2-d WC and improved it.

This problem was solved by "pause" - move after which there is VCT win.

But in this problem if Black play this "pause" - move 1 at Dia 2-3, white play three move 2 !, the idea of this move is to add Black stone at point 5, after that move 11 is not "pause" , there is no VCT win because of overline 1-7-x-x-x-5, this move became only "yobi".

And it is possible to stop this attack on VCT.

Only program of Mr. Zhang - Super able to win this position.

Other programs can not, Blackstone make move wrong 1 move according Dia 2-3.

 

 

 

 

 

 

 

Problem N3 White move

     Dia 3-1                                          Dia 3-2

 

If White don't play moves 1 and 3 ! they lose, if they play this moves Black will lose.

IK and Blackstone solved this problem.

Super and Five Eyes can not Solve.

 

 

Problem N4

Black move.

 

 

Dia 4-1                                               Dia 4-2

 

This problem is rather easy. White treat to make 4-3-3 at point 15.

But Black can play VCF, and convert one of three to the future 3-3, so there is no foul in point 15 anymore.

Super, Five Eyes , Blackstone can solve it.

 

Problem N5

Black move.

Dia 5-1

Dia 5-2

 

Black plays three move 1 at dia 5-2, then fours moves 3,5 and brilliant fukumi 7 !

The only Blackstone can find it.

 

Dia 5-3

Most of programs play 3 move as it is shown at  Dia 5-3, but seems they don't calculating possibility to shot by four 8 during three.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Problem N6

Black move.

Dia 6-1

Dia 6-2

Only Blackstone can solve this problem.

First, Black play some fours and then they play 13 move  three - "misey".

 

 

Problem N7

Black move

Dia 7-1                                     Dia 7-2

Nice 7 move contrchack (nori)

Super, IK, Blackstone solve it.

 

Problem N8

White move.

Dia 8-1                                               Dia 8-2

 

Move 2 fukumi !

If   3-A 4-4

 

One more win the same idea but with "pause" see dia 8-3, 8-4

 

Dia 8-3                                               Dia 8-4

This problem was solved only Blackstone.

 

 

Problem N9

White move

 

Dia 9-1

 

Dia 9-2

 

This problem was not solved by computers .

 

Problem N10

Black move

Dia 10-1

 

 

 

 

 

Dia 10-2

Black plays move 1 dia 10-2 fukumi !, then VCT victory

 

Dia 10-3

If Black don't play fukumi they can get overline.

Programs can not solve this problem.

 

So, Final Results of WC - solving

Because of 2-d WC champion Blackstone participated in this WC solving not in the list of participants, the first place in 3-d WC Solving won "Super" by Zhang Tongxiang (China). Author is working at Japan , Tokyo.

He will receive Cup of winner 3-d WC Solving Problems.

But the Rules of this 3-d WC let participants to send their problems.

May be next time Organizing Committee will be able to add some additional stones in not important places to prevent "memory solutions".

 

Seems that "Blackstone" program  is still the strongest program in Solving Problems.

 

Next World Championship among Computer Programs will be in 2001 year, November. We will have one more Gomoku Tournament (N-Rule).

Programmers have time to improve their software, see you next time at next WC among Computer programs !!!
