Abstract

For the first time, the recently proposed Jaya metaheuristic optimization algorithm (JA) is used for optimal design of water distribution networks (WDN’s). This algorithm has no control parameters, which eliminates the exhausting computational effort required to carry out the essential tune up step for these parameters. A new variant of the algorithm, named free sensitivity analysis Jaya algorithm (FSAJA), is suggested to be free from even the common metaheuristic algorithms parameters, i.e., population size, number of generations and penalty function. Six different variants of the proposed algorithm are investigated to settle the best one using a recently developed two performance criteria. Three famous benchmarks WDN’s and a national one, are solved to examine the algorithm. Comparing the performance of FSAJA, with JA and the various evolutionary algorithms available in the literature shows the promising effectiveness, efficiency, and robustness of the proposed algorithm. A new global minimum is achieved for the national WDN.
