Due to the economic crisis and water scarcity happened in recent years, many researchers focused on the water distribution network optimization problem. On this specified subject all recent research applied stochastic meta-heuristic algorithms to solve these sets of problems. In this study, the application of a novel deterministic physically-inspired heuristic algorithm for minimizing cost of pipe-sizing in the water distribution system (WDS) is investigated. In fact, the algorithm used in this research is the modified central force optimization algorithm to solve water distribution network problem called CFOnet. The approach is applied to optimize the design of Kadu and Khorramshahr networks. For this purpose CFOnet method is programmed in MATLAB and interfaced with the hydraulic simulation model, EPANET. The obtained solutions in this study are compared with those stochastic methods in the WDSs optimization literature. This comparison shows that CFOnet is more efficient in obtaining lower cost rather than other optimization methods for solving two mentioned WDSs while it enjoys the merits of a deterministic optimization method.
