Web31 May 2024 · Is there a way in DEAP to use more than one mutation or more than one crossover with their own probability? The algorithms expect 'mate' and 'mutate' to be registered in the toolbox. I can technically create my own function that chooses which mutation to use based on a random value and pass it as the operator. WebEach permutation in parent individuals is executed by a partially matched crossover [15] shown in Fig. 2. The partially matched crossover can guarantee child permutations feasible.
