{wiki=Fitness_function}
A fitness function is a crucial component in optimization and evolutionary algorithms, serving as a measure to evaluate how well a given solution meets the desired objectives or constraints of a problem. It quantifies the quality or performance of an individual solution in the context of the optimization task. The fitness function assigns a score, typically a numerical value, to each solution, allowing algorithms to compare different solutions and guide the search for optimal or near-optimal outcomes.
