Berserk 4.3.0 is officially released

.

Another large release for Berserk, the biggest change in this patch being fully-phased move generation allowing for a massive speed-up. Self play results showed ~160 Elo in VSTC and ~130 Elo in LTC. Hoping that 50% of this self-play Elo bears fruit

That's stunning!

Nalwald 1.10 release.
Self-play (against Nalwald 1.9) improvement is around 100 Elo, considering previous releases this may translate into a true improvement of 60 Elo.
Changes are, among others:
- added fail-high delta pruning
- replaced futility pruning with futility reductions
- generated additional optimization data
- now all eval parameters are tapered

Another large release for Berserk, the biggest change in this patch being fully-phased move generation allowing for a massive speed-up. Self play results showed ~160 Elo in VSTC and ~130 Elo in LTC. Hoping that 50% of this self-play Elo bears fruit
That's stunning!

Self-play (against Nalwald 1.9) improvement is around 100 Elo, considering previous releases this may translate into a true improvement of 60 Elo.
Changes are, among others:
- added fail-high delta pruning
- replaced futility pruning with futility reductions
- generated additional optimization data
- now all eval parameters are tapered

Put your engine in the following pool:

Code: Select all

 1. ProDeo_2.2 2717.7 [2717.7]
 2. Orion_07 2743.3 [2730.5]

- +87 elo points against Stash 19 (rated 2495 again)
- +249 against Zahak 3.0 (rated 2407) (which I believe is an exaggeration)
- +116 against Lozza 2 somehow (even though it is rated 2560)
- -112 against Supernova 2.3 (rated 2650)
- -70 against Nalwald 1.9 (expected to be around 2630)

So yeah, I fail to guess a better range, sorry

P.S. All matches are 400 games or more
