Chaos Genetic Algorithm Based on Niche of Water Resources Optimization Scheduling Research

Scheduling of water resources has characteristics of multi-objective,large-scale and uncertainty.To a certain extent,chaos genetic algorithm can avoid local optimization and increase solution speed for water resource scheduling problems,but this algorithm damages population diversity and leads to lower solution precision.So a chaos genetic algorithm based on niche(NCGA) was proposed in this paper.This algorithm can protect population diversity by retaining source center individual of niche technology.At the same time,the algorithm combines fast convergence of the genetic algorithm with randomicity,ergodicity and regularity of chaos to improve solution speed and precision.Applying to the water resource optimization scheduling model,simulation results show that the proposed algorithm is more reasonable and efficient than chaos genetic algorithm for allocation of water resources and has comprehensive benefits.
