New Android UCI engine: Ethereal r745

Ethereal is an engine under regular development progress by Andrew Grant. According to its author, who hopefully started to compile for Android too starting from this release, Ethereal is capable of beating MicroMax and TSCP, which means it may reach 2000 ELO in Rapidroid.

Below remarks are taken from the author's description:
"Ethereal is a UCI compliant chess engine which uses a BitBoard board representation and an alpha beta pruning framework. Additionally, the engine uses the follow improvements to pruning, move ordering, and other time saving methods; Null move pruning, Razoring at pre-frontier and frontier nodes, Delta pruning in the quiescence search, Late move reductions in the main alpha beta algorithm, Null windows for principle variation searches, a transposition table, and finally, a killer move heuristic. This engine was originally developed to give myself a worthy opponent, but has since become a worthy opponent for other chess engines. This engine can compete with various engines in the lower rankings of the CCLR tier lists. Some of those results are noted at the bottom of this readme."

I'm planning to test Ethereal as soon as possible and add it to the ranking in next release, in case it works without problems.

Alex i didn't delete any comment here. I put yours again: Hi Gurcan.
A few days ago I asked from Mincho Georgiev to made some build's for android, so, new pawny 1.2 engine is ready, but, the developer needs help/reports about arm builds, because he doesn't have arm devices.
I think you can help him, because I don't have the necessary knowledge:( On this site you can download the engine and send your feedback about arm builds. http://pawny.netii.net/ Try to contact with him. Thanks.

Sayuri was updated on June 19 again: https://github.com/MetalPhaeton/sayuri/blob/master/SayuriCompiled/Android/. Unfortunately the author deletes old versions. Those who collects engines need to be more attentive.

I keep all june builds. The problem is that May and june builds all exit in the beginning of the games. For me last ok build is 2016.04.09. What is your experience with recent versions?

Etheral 7.45 makes instant moves. Not qualified... I try now 7.49. It plays but very weak. There's something with the compile.

Alex said...

Okay Gurcan, now I see the comment. The funny thing is that, I posted my comment three times yesterday, and after some time, my comment disappeared. Anyway, the pawny engine not working, developer will try to contact with Aart Bik. That's all I know.

Ignore my previous comment about Ethereal. Andy Grant has released v7.49 but the Android build remained the same. It's still v7.45. The reason i see it playing is that the device was different. The Android build is absolutely below 1000 ELO. Better wait for a healthier one.
