FOREST, my Reversi program

FOREST is a Reversi program which dates back to 1978. Initially, it was written in an obscure teaching language and was laboriously running on the mini-computer at my school. Though it has improved greatly over time, it is still based on the same principles and algorithms as the original version. The program's name, FOREST, is due to the large number of trees it conceals.
