Implementing Chromosome Repairment
Explore how to implement chromosome repairment in genetic algorithms to maintain solution validity after crossover or mutation. Understand different crossover strategies and when repairment is necessary, especially for problems like N-Queens. Learn to enhance algorithm reliability by repairing chromosomes, enabling the use of limited crossover strategies without losing solution integrity.
We'll cover the following...
What is chromosome repairment?
Sometimes, we’re limited in the crossover strategy we can use. In the lesson Optimizing Cargo Loads, we explored a solution to the N-queens problem that wouldn’t work because we used single-point crossover.
One approach that works around limitations in crossover strategies is the concept of chromosome repairment. Chromosome repairment is the process of ensuring solutions remain valid after crossover or mutation. In the case of N-queens, using single-point crossover ruins the integrity of the permutation. This means after ...
