Detailed Description
- Description
- ParallelGA implements a Simple Genetic Algorithm, some features are:
- you can customize Reproduction process using setReproduction
- you can customize, of course, the Fitness function using setEvaluation
- it use a multi-thread approach for parallel evaluation of Genotypes (see numThreads)
- Warnings
