Arminius Source [1]

a chess engine by Volker Annuss, which is a complete restructured successor of Hermann [2]. Both engines, Hermann and Arminius use a neural network to calculate a probability how likely it is in iterative deepening that the best move will change when searching one ply deeper. They both use properties of the position and results from previous iterations that are correlated with a change in the best move in the next iteration. Arminius also considers relative node counts [3]. Arminius' tournament debut was the DOCCC 2011. Arminius 2017, the version that won the third place at PT 51, is using its own format of 6-men WDL endgame bitbases [4]. In August 2017, Arminius started to practice Black Magic [5].
