Chess engine: Winter 3.0



Winter
is a chess engine that relies on the UCI protocol to communicate with a GUI.

Contributors: Jonathan Rosenthal, Jonathan Maurer, Jonas Kuratli.
Rating CEDR=3262 

v.3.0:
This version features a completely new network architecture which can be interpreted as a form of Graph Neural Network. To my knowledge Winter is the first engine to adopt such an architecture.
