Selecting only the fittest chromosome for reproduction in genetic algorithms

Let's assume I track all my chromosomes with the fittness level in a database. The initial population will contain all available allels at least once. So, every solution exists at least in one ...

Mutation on demand in genetic algorithms

genetic algorithm usually use a "mutation rate" to control the rate of chromosome mutation. Most of the researchers at researchgate recommend to keep this rate low in order to converge quickly, to be ...

Is there any advantage in using Particle Swarm Optimization for clustering than K-Means?

I have read some paper about using particle swarm optimization. It doesn't look give much different result than K-Means. I tried to use PSO for clustering but the result is pretty much the same with K-...
