Interesting stuff and another toy to play with
Digging for hidden chess engines regards,
Dr.D

Wonder if Ed would let him work on ProDeo to make it SMP?

Maybe he could talk to the Gromit/Anaconda developers to make it SMP as well. One of my fav's from the "olden days"

It would be a great idea Cliff

Thank you Dr. Deeb

How do we go about getting the parties together?

Since I started that post at TDDB, I might as well answer. Somebody submitted an older Crafty source-code based on this link: http://www.cs.ubc.ca/~jiang/ .

Here's the abstract:

FIRST EXPERIMENTAL RESULTS OF PROBCUT
APPLIED TO CHESS

Abstract ProbCut is a selective-search enhancement to the standard alpha–beta algorithm
for two–person games. ProbCut and its improved variant Multi–ProbCut (MPC)
have been shown to be effective in Othello and Shogi, but there had not been
any report of success in the game of chess previously. This paper discusses our
implementation of ProbCut and MPC in the chess engine 􀀀. Initial test
results suggest that the MPC version of 􀀀 is stronger than the original
version of 􀀀: it searches deeper in promising lines and defeated the
original 􀀀 +22􀀀􀀀   (59.4%) in a 64–game match. Incorporating
MPC into 􀀀 also increased its tournament performance against  –
another strong chess program: 􀀀’s speed chess tournament score went
up from 51% to 56%.

This Crafty is based on Crafty v18.15 but quite a challenge to compile. I could only build an SP version with only basic optimization. Maybe Jim could help me here. It's quite a strong engine too.

GambitFruit4bxSE on the other hand is a fun engine project where I'll slip (as much as I can, the latest additions that I could leak in our development ). I for one am still waiting for the next official release. The general rule should be around +30 elo at the minimum.

I'm just keeping the forum active, starting again my engine testing seriously, and practicing to compile ( and revive) old forgotten open-source engines...nothing else to do at home!

Any chance you could upgrade ProDeo to SMP? I hope Ed would not mind. Would love to see how that classic engine would improve!

Yes indeed. I couldn't believe how lucky GBF4bxSE is ! It just proves that the improvements of Toga 3.1.2SE from Toga 1.3.4 gives a considerable boost on other Fruit-based engines.
