John Tromp's Fhourstones connect-4 solver results are included below.

Fhourstones connect-4 solver benchmark is an implementation of the
well-known game played on a vertical board of 7 columns by 6 rows, where
2 players take turns in dropping 'stones' in a column. The first player
to get 4 stones in a horizontal, vertical, or diagonal row, wins the 
game. The game is drawn if there is no winner after 42 moves.

This Fhourstones implementation (software) is copyright (c) 1992 by 
John Tromp (tromp@cwi.nl).

Some technical notes:
Of the full 49 bit lock that describes a connect-4 position, only 32 bits
are stored in the hashtable entry while the remaining 17 are subsumed in
the hash-address. To also accomodate 8 fold probing, a minimum of one
million hash table entries are required. The benchmark uses just over
5 MBytes of memory. The potentially expensive modulo operations are
implemented with repeated table look-up. The use of small integer sizes
is available as an option ('-DSMALL' default). Although this benchmark
emphasizes random access performance, it also exercises standard scalar 
performance; the recursive alpha-beta calls, incremental threat table 
computations, history table updates, and move-reordering represent a fair 
mix of scalar operations. Fhourstones is an 'integer' type benchmark.

The Fhourstones program (c4.tar.Z.uue, c4.doc, and c4run.doc) and latest
results (c4.tbl) can be obtained via anonymous ftp from 'marlin.nosc.mil'
in directory 'pub/aburto'. The 'marlin' host (IP) number is: 128.49.16.4

Please send new results (new machines, compilers, compiler options) to:
aburto@marlin.nosc.mil. I will keep the results up-dated and post
periodically to 'comp.benchmarks'. Any comments are greatly appreciated
too.
