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.4.0: v4 uses a bigger network, loads weights from a file and has some minor optimisations. The network was trained with trainer.js using self-play data generated with datagen.js. Please use the latest version of Node for best performance:- https://nodejs.org Note that Lozza 4 will not start unless Node v20 or above is used.
