Chaotic artificial fish-swarm algorithm and its application in water use optimization in irrigated areas

The chaotic artificial fish-swarm algorithm is presented combining the artificial fish-swarm algorithm with water resources optimization. The chaotic artificial fish-swarm algorithm was used to solve the problem of the water utilization optimization for crops in water saving irrigation region, Weihai city, Shandong Province. The result indicates that food planting area is decreased, the economic crops planting area is increased and the net benefit is increased by 56 percent, and the algorithm can search the optimal value and the algorithm is effective and practical. The algorithm provides a new method for optimization of water allocation in irrigated areas.
