Abstract The slime mould algorithm (SMA), as an emerging and promising swarm intelligence algorithm, has been studied in various fields. However, SMA suffers from issues such easily getting trapped local optima slow convergence, which pose challenges when applied to practical problems. Therefore, this study proposes improved SMA, named HESMA, by incorporating the covariance matrix adaptation evolution strategy (CMA-ES) storing best position of each individual (SBP). On one hand, CMA-ES enhances algorithm’s exploration capability, addressing issue being unable explore vicinity optimal solution. other SBP convergence speed prevents it diverging inferior solutions. Finally, validate effectiveness our proposed conducted experiments on 30 IEEE CEC 2017 benchmark functions compared HESMA with 12 conventional metaheuristic algorithms. results demonstrated that indeed achieved improvements over SMA. Furthermore, highlight performance further, 13 advanced algorithms, showed outperformed these algorithms significantly. Next, five engineering optimization problems, experimental revealed exhibited significant advantages solving real-world These findings further support practicality complex design challenges.

Water distribution networks (WDNs) are vital infrastructures designed to ensure a minimum acceptable supply level consumers under different operating conditions throughout the design period. Due their complexity and substantial investment required for construction maintenance, economic aspects have become primary focus researchers engineers. Various evolutionary algorithms (EAs), such as genetic algorithm (GA), been utilized achieve cost minimization while fulfilling hydraulic requirements. This study uses Parallel Slime Mould Algorithm (PSMA), variant of slime mould (SMA) developed by Wang et al., implemented solve mathematical optimization WDNs. The PSMA incorporates Hazen-Williams equation calculating head loss pressure constraints feasibility solution. proposed method is applied benchmark network compared with results from GA used Savic. proved effective in optimizing WDN, achieving reduction approximately 6.08% maintaining feasibility. However, pipe sizes showed notable differences, favoring larger diameters most pipes except 2. These highlight potential powerful tool WDN optimization, particularly when priority.
