toernooiselectie

Toernooiselectie, also known as tournament selection, is a method used in evolutionary algorithms and genetic programming to select individuals for reproduction. This process is crucial for the evolution of a population towards better solutions. Tournament selection works by randomly choosing a subset of individuals from the population and then selecting the best individual from this subset to participate in reproduction. The size of the subset, known as the tournament size, is a parameter that can be adjusted. A larger tournament size increases the pressure for selection, potentially leading to faster convergence but also a higher risk of premature convergence, where the algorithm gets stuck in a local optimum. Conversely, a smaller tournament size reduces selection pressure, allowing for more exploration of the search space. This method is popular due to its simplicity and effectiveness in balancing exploration and exploitation. It is often used in conjunction with other selection methods or as a standalone technique in various optimization problems.
