I need to try harder.

What are you trying to achieve?

The CIL Toolkit has a random game generator that's used in testing. The routines involved support validation routine hooks, so generating lots of random games helps test many of the toolkit's internals. And the longer the game, the better.

Supplying the move text to others helps them test their programs.

The program just finished a 100,000 game test run. The longest game was 867 ply and the average ply length was 335.97982 (just under 168 moves per game). The game termination status breakdown:

Code: Select all

checkmate                  15429  0.1543
fifty moves draw           19865  0.1987
insufficient material draw 56138  0.5614
position repetition draw    2496  0.0250
stalemate                   6072  0.0607

read fine into crafty...

It loads okay into Symbolic when it's read in as PGN. But the command line interface is limited to 255 tokens, so it takes multiple pastes when done interactively.

Doesn't bother me since there were linefeeds in the text. If it were all one line, it would not get parsed correctly however.

The newlines were inserted by the Lisp interpreter whose pretty printing subsystem is sensitive to the terminal width (if applicable) of the output stream. There is a way of turning off this behavior, but I haven't tried it yet.

I'm about done with the random game testing for now. With the VAN (visit all nodes to depth) tester working along with the FEN decoder, I can use position test suites. VAN handles nodes at about 8 KHz for the initial array when running on the bytecode processor.

It would be nice if someone were to construct a magical 5300+ move longest game score.

A recent 100,000 random game test:

Code: Select all

Total move count: 33680017
checkmate                  15012  0.1501
fifty moves draw           20200  0.2020
insufficient material draw 56131  0.5613
position repetition draw    2613  0.0261
stalemate                   6044  0.0604

The longest game had 814 ply. Here it is without newlines (and again, with move numbering):

the longest game had 814 ply.

It looks like it would be easy to length this significantly by adding a bunch of repetitions between each pawn move. Not sure why you are trying to do it, but adding enough repetition between pawns moves (move several pieces to a bunch of squares and back) somewhat systematically would probably get you 6000+ pretty easy.

Yes. Another idea would be to do a small minimax search that selected the "best" move avoiding captures and pawn moves.

Bu my main goal here is to use random games to test out lots of code that might otherwise be missed.

The random game generator also tracks maximal move counts. Here's the best position so far from recent testing:
