Blitzoid chess engine ratings for Android: TEXEL 1.04 ADDED!

One fair method to compare an engine update vs previous version is to make it play exactly the same games, when this doesn't require thousands of games and very long time.

This had worked well with Stockfish 5 vs Stockfisd DD recently. So, i managed the same process with Texel v1.04 to compare it to Texel v1.03.

Once again, it seemed to be highly efficient.

After 248 games against the same opponents as Texel 1.03, the new version has performed +49 ELO better, reaching 2609 and overtaking Gaviota 1.0 to become #7 among strongest Android chess engines available.

Another usual tendency that was confirmed once again, is that the ELO improvement measured against other engines is lower than the one measured against the previous version of the same engine. That was exactly the same case with Stockfish.

With Texel 1.04 added, we have now 91 engines in Blitzoid ranking. I will be probably adding Discocheck 4.3 to the next release. I'd previously disqualified that version due to engine disconnection problems arising but it may be that my cpu settings at that time caused the error. To follow...
