SMIRF (an acronym for Strategiespielprogramm mit intelligent rückkoppelnden Funktionen) is a Windows chess game. It implements an appropriate innovative variant of an adaptive recursive feedback algorithm. The procedure cuts the to-be-evaluated search tree effectively both in depth and in width. Creating an optimally efficient chess engine is a touchstone of artificial intelligence research. Thus, this approach is associated with artificial intelligence. The creation of such software is a goal of the SMIRF project.
