2nd Crazyhouse Computer Championships 2017

[Ferdy]

Hi Ferd,

Here is Nebiyu146a cross compiled to windows. Let me know if you have problems with it.

regards,
Daniel

Here are the issues I found.
1. With ht set to 256, it will actually use 800 by looking at the windows task manager.
2. I am using cutechess gui/cli and it does not see nebiyualien as able to play crazyhouse because it does not see crazyhouse as one of the declared variants. This version has only, 8x8+5_crazyhouse. But there is a way to trick cutechess so this is just a minor issue.
3. There are disconnects that I observed in the test. I did not investigate further, this can be better observed thru winboard with debug on. This did not happened in 1.45.

4. I run nebiyu thru inbetween to convert text from engine to gui and gui to engine because of the way nebiyu sent promotion moves. This has worked in 1.45.

[Daniel Shawul]

Ferd,

The reason why nebiyuAlien allocates 800mb is because its data structure for MOVE is too big (about 28 bytes), not because of allocating extra hash entries. I have similar issue with the checkers variant as well that has unknown jump lenghts (current set as 11 to squares).
I have reduced the size by a factor of 4 now.

I noticed nebiyu is not able to play variants in winboard standard edition, so i think it is best to ask H.G. why that is.

No idea why it disconnects.

It maybe better to use 1.45a without montecarlo for now.

Yes that was what I thought to use 1.45a instead and started the candidates now.

Hi Ferd,

Do the disconnects happen when nebiyu resigns ? It seems cutechess-cli has a problem when an engine resigns by itself. Someone else reported to me that this also happens in Scorpio + cutechess-cli so one solution was to set the resign value so high that it doesn't resign. But this issue seems to be a problem of cutechess-cli.
