Applied of Central Force Algorithm (CFO) in Optimization of Irrigation WaterDistribution Network

Since water distribution networks have very high execution costs, it is essential to discuss the optimal design of these types of networks. In this research, Central Force Optimization (CFO) was used to optimize Ismail Abad irrigation water distribution network. This network that is pressurized network and includes 19 pipes and nodes 18. Optimization of the network has been evaluated by developing an optimization model based on CFO algorithm in MATLAB and the dynamic connection with EPANET software for network hydraulic calculation. Central force algorithm for conditions of probes 42, 15% mutation rate, the number of iteration equal to 1,000 (Nt = 1000) and initial acceleration probe is zero showed the best performance. The optimal solution for Ismael Abad irrigation water distribution network show that CFO (737,924 $) is %1.55 more than the absolute optimum (Shahinezhad, 1390) that determined by the MILP method.
