Fizbo 1.6 released

Post by Graham Banks »

From Youri

Fizbo version 1.6 has just been released, and can be downloaded from https://sites.google.com/site/fizbochessengine/

Changes in version 1.6:
1. fixed a timing bug - now engine should no longer time out.
2. fixed a bug in EGTB logic - now engine should work when only 4-piece (and not 5-piece) syzygy tables are present.
3. fixed a bug in main transposition table - now it can be made larger than 2Gb.
4. added option "UseEGTBInsideSearch": when set to false, engine will only use EGTB in root position, not inside search. This allows EGTBs to be used when they are stored on hard drive and not on SSD.
5. various small modifications to search and evaluation, resulting in approximately +30 ELO for 1 core play.
6. multiple changes to parallel search, which now should work as intended. Estimated benefit from running on 4 cores is around +90 ELO.

Youri.

Hi Graham,

nice, the reported bugs are fixed.
No 4-pieces and all the time-forfeits ...

THANKS to the programmer!
So I have a lot of lesser work with my test-runs.

Best

I am having problems with the recent version of Fizbo. I ran a couple of games on Arena, but Fizbo always lost on time around the move 20-30, when it had more than enough time (I was running a continuous time control with 5 min per 40 moves).

I'll alert Youri to this.
