Subject: move count frequency

Author: Chris Whittington

Date: 06:49:55 12/08/97


The table below shows 'move count' and 'frequency' for CSTal genmoves on
the entire BT2630 test suite at 10 seconds per move.

frequency is the number of times genmove generated N moves during the
searches. ie. there were exactly 8 moves arising  from a node, 1147
times. The max frequency was 1 move, this occurred 10001 times, and the
min frequency was 61 moves which occurred once. The were no hits at all
at 62 moves and above.

I guess that the high figures at 1 to 4 moves or so, is maybe due to the
search's desire to travel down more forcing lines; or maybe, more
likely, reflects  replies to check. The relatively few counts at 0
probably reflects CSTal's ability to calcualate mate and stalemate in
its evaluation function, and thus not need to tack on an extra level of
search to prove this.
