Topple v0.3.4 released

[konsolas]

So I tracked down several search bugs and improved Topple's search and evaluation for some hopefully significant strength increase.

The release and binaries can be found here: https://github.com/konsolas/ToppleChess ... tag/v0.3.4

Self play shows a gain of around +80, but, as I found from my release of v0.3.0, this value is unlikely to be very accurate.
I haven't been able to test v0.3.4 against many other engines yet, so I'm not fully sure about the elo gain.

Thanks in advance to anyone testing v0.3.4

Nice, improving fast it seems!

I tested version 0.3.3. The binary Topple-core2.exe worked fine on my AMD Phenom II x4.

I tried Topple 0.3.4 Legacy, because it is the only one that does not crash when I double click on it, but when I start a tournament on Winboard, it appears an error message and Topple exits Winboard.

A 4'+2" tournament with 0.3.3 version:

That's strange - does winboard log UCI communications with the chess engine?

Could you perhaps try sending Topple some UCI commands manually?

e.g.

Code: Select all

uci
position startpos moves e2e4 e7e5
go movetime 1000

and see if there is reasonable output without crashes?

Topple-legacy is compiled with the same options as Topple-core2 was, or at least it should be.

Topple-legacy is compiled with the same options as Topple-core2 was, or at least it should be.

It accepts those commands without crashing.

This is the error message showed by Winboard 4.6.2:

POLYGLOT: pipex_exit(): Topple-legacy.exe: child exit unexpectedly.

PS: Also crashed on Arena 3.5.1

On my machine, sending those commands to Topple does not appear to cause a crash, so it might be an issue with the architecture specific optimisations that have been enabled.

Here is a build of Topple v0.3.4 compiled for a generic x86-64 CPU: https://transfer.sh/5463b/Topple.exe

This version works fine, thanks.

As I wrote before, when I tried those commands on console mode, Topple did not crash. The problem was when it ran in the GUI: after Topple found its best move, it crashed.
