Stoofvlees Ingredients [1]

an experimental chess engine by Gian-Carlo Pascutto. The evaluation function consists of a set of feature recognizers coupled to a neural network, which was trained with an oracle [2], that is the evaluation was entirely automatically learned from "watching" Grandmaster games [3]. The results were incorporated into Deep Sjeng [4]. Stoofvlees played the ICT 2007 operated by Elke Van Vlierberghe, along with its relative Deep Sjeng.

Stoofvlees II

In 2019, an updated version dubbed Stoofvlees II was announced to play chess at CEGT, with neural networks instantiated on Nvidia GPUs [5] [6]. Stoofvlees II hat its TCEC debut at Season 16 starting in July 2019, where it became runner up at the qualifier, to win three following divisions, the second division, the first division and the playoff for the premier division, finally finishing as strong fifth, and establishing as top contender in that top league in subsequent seasons.
