A preview : How is the TSP problem defined? What we know about the problem: NP-Completeness. When running the genetic algorithm, the highest fitness of each generation barely ever exceeds the fitness one would expect from a snake without input (in this case 16), which I suppose is correlated to the issue with the neural network. The first one is configured to use the Microsoft C/C++ compiler and the second one uses the Intel C++ compiler. The two complex issues with using a Genetic Algorithm to solve the Traveling Salesman Problem are the encoding of the tour and the crossover algorithm that is used to combine the two parent tours to make the child tours. I am new to genetic algorithm so if anyone has a code that can do this that would help me start off will be greatly appreciated. Algorithm- Genetic Algorithm works in the following steps- Step-01:. It differs from the generic GA in that tournament selection does not replace the selected individuals in the population, and instead of adding the children of the selected parents into the next generation, the two best individuals out of the two parents and two children are added back into. The genetic algorithms are useful for NP-hard problems, especially the traveling salesman problem. It is a very efiective algorithm but has been generally criticized for its computational complexity, lack of elitism and for. Specifically the following - Page on Mit.
