Island model strategy

[G3r4rd00]

Title: Implementation of Island Model Strategy in Genetic Algorithm

• Implemented the Island Model Strategy, dividing the population into subpopulations (islands) that evolve independently.
• Each chromosome is assigned to an island either cyclically or through random migration based on a migration probability.
• Added a dynamic migration mechanism, allowing chromosomes to switch islands with a certain probability in each generation.
• Crossover is performed locally within each island, improving diversity without sacrificing convergence.
• Optimized the cleanup of the island mapping to remove references to deleted chromosomes.
