help me test multipv

[brtzsnr]

Hi!

I'm adding multipv to my engine for analysis and later Skill Levels [1]. This is a new option and may change the interaction with GUIs. Could you help me test it? I have no experience with multipv analysis and Linux SCID doesn't support multipv afaik. On my initial command line tests, it works good.

If want to help me, please PM me. I will compile and send you a binary for your favorite OS and architecture.

This is a 2600 Elo engine so don't expect very strong analysis. I'm interested only in the interaction with the common GUIs.

Thank you,

Thank you,

I could test your engine in the tourney mode of Satana (it is not a "common" GUI).

Thanks Stefano!

Does your tournament test multipv too? I don't need regular engine vs engine testing. Thanks to Graham, Ed, HGM and others I get enough of that. Multipv is mostly for humans.

For engine vs engine feel free to use the latest downloadable version from https://bitbucket.org/zurichess/zurichess/downloads. That one is quiet stable.

Satana-tourney works in console mode, so it is not for humans.

I've tested zurichess-glarus-windows-386.exe and works perfectly in Satana-Tourney mode.

Here is the link to the amd64 exe that supports multipv: https://drive.google.com/open?id=0B2uKL ... DdGR056TUk

[elcabesa]

your uci command reply is wrong

option name MultiPV type spin default 1

should have been:
option name MultiPV type spin default 1 min 1 max 24

for example

[hgm]

The UCI specs do not say that the 'min' and 'max' parameters are required, right? So if there is no maximum to a spin option you could just leave it out.

[cdani]

In ChessBase your multipv does not work. I don't know if there is the possibility to view some log.

In Arena 3.0 the gui does not shows the multipv only the first move, in the log shows fine the multipv
