Fitness

In computer science, particularly in the context of evolutionary algorithms and optimization problems, "fitness" refers to a measure of how well a particular solution or individual performs in relation to the problem being solved. Fitness is often quantified by a fitness function, which evaluates and assigns a score based on various criteria relevant to the optimization goal.In genetic algorithms, for instance, individuals in a population represent potential solutions, and their fitness scores guide the selection process for breeding the next generation. The individuals with higher fitness are more likely to be selected to reproduce, promoting the survival of the most promising solutions over subsequent generations.Fitness can be applied in various domains, including machine learning, where it might correlate to the accuracy of a model, or in game AI, where it could evaluate performance in gameplay scenarios. The concept emphasizes the effectiveness of solutions in achieving objectives and drives the evolutionary process in algorithms aiming for optimization.
