Evaluation Function

An evaluation function is a tool used in computers and artificial intelligence to assess and assign a score to a particular situation or position. For example, in chess, it helps determine how favorable a board setup is for a player by considering factors like material, position, and control of the board. The higher the score, the more promising the position. This function guides decision-making by helping the system choose the best move, aiming to maximize advantages or minimize disadvantages based on the evaluation. Essentially, it quantifies the quality of a scenario to inform strategic choices.
