Path planning for mobile robots poses a challenging optimization problem, requiring the discovery of near-optimal path within diverse constraints. Conventional particle swarm (PSO) algorithms encounter limitations in solving constrained problems, vulnerability to local optima, and premature convergence. To address these challenges, this paper proposes bi-population PSO algorithm with random perturbation strategy (BPPSO), which divides particles into two subpopulations. The first subpopulation enhances global search capabilities by considering quality optimal solution randomly selected when updating velocities. second strengthens using linear cognitive coefficient adjustment strategy. Moreover, counter tracks iteration without improvement best position. Upon reaching predefined threshold, is added positions all both subpopulations, increasing diversity enhancing ability escape optima. performance BPPSO was experimentally validated across three benchmark functions four environment models. results have demonstrated that proposed outperforms existing other established terms running time, highlighting feasibility resolving challenge robot planning.
