Chess engine (java): Lozza 2.1

on

Lozza - Javascript chess engine inspired by Fabien Letouzey's Fruit 2.1. Lozza was an exercise in principal variation search and hand-coded evaluation. It's easy to use Lozza into your web projects. Communication is via the UCI protocol, which also allows it to be used offline in chess user interfaces via Nodejs (etc.).

v.2.1
Version 2.1 has been retuned with a new gradient descent tuner. It also has some minor search optimisations and evaluation tweaks: non-linear mobility, tightness and tension.
To run Lozza in a chess UI like Arena, Winboard, Cutechess and Banksia etc., download lozza21.zip, unzip and follow the notes in release.txt.
