WinHonte - perhaps the first program using the neural network algorithm. plays at the maximum level ~ 5k. Size: 826 KB
https://winhonte.software.informer.com/download/WinHonte got a favourable review in the AGA E-journal #64:
"... I saw immediately just how much go programming had improved."
"... I was particularly impressed with WinHonte's tactics; it came up
with clever sequences often enough that it couldn't be by accident."
"... Most surprisingly, WinHonte plays very much like a human, making
similar moves and mistakes to other players of its level. WinHonte's
author rates the playing strength of the program at 4-9 kyu, an
assessment that seems fair from my experiences."
"...Overall, I found WinHonte to be a worthwhile go playing program.
Its low price ($30) compares favourably to competitors, and it is
strong enough to give beginners a good game."
2004 program! but plays better than some new programs!
(this free trial version of WinHonte only plays and evaluates at level 1 when more than 100 stones are on the board)
any boards 9x9 - 19x19, 100 moves are usually enough on small boards.
maybe someone has preserved the full version? interesting to see. write in pm
