My Xmas gift for CCC

[Sylwy]

Hello folks !

Do you still remember Mr. Ruxy ???

I cut off for a few moments my four months boycott (sorry Robbo-Equinox, Miky & Ochoa team ) for a little gift: SHUTRANJ the first chess engine coming from Pakistan (via Leicester - United Kingdom).
The author is Mr. Okash Khawaja - Senior Software Engineer at Draycir Ltd Leicester.
Shutranj is a chess engine written is C# 5.0. Like features:

• evaluates over 119 million positions in ~1.4 seconds;
• bitboards for board representation, NegaMax search with Alpha-Beta pruning;
• lockless parallelised search including a shared hash table;
• search optimisations: Aspiration Windows, Killer Heuristic, Transposition Tables, Move Ordering, Iterative Deepening;
• basic Universal Chess Interface (UCI) support.

The engine has around 1800 ELO.

I received also the binaries (working only on Win Vista, 7 & 8) from its author like a Xmas gift !

Maybe somebody here will build a binary working also on Win XP (Mr. Tony Mokonen, Mr. Velmarin ???...........).

The source code is here:

Have a nice day !

Thank you for the information, Mr. Ruxy!

119 million positions in 1.4 seconds?! Does it run on quantun computers?

Looks like the evaluation is only material and PST. Then, I guess it may be possible that the time spent in eval is very very short. Maybe the author measured eval() it in a loop.

Thanks Ryx!!

But...

so many moves examined for such a paltry Elo!!

Perhaps too much brute force approach
