The poor and rich optimization algorithm (PRO) is a new bio-inspired meta-heuristic algorithm based on the behavior of the poor and the rich. PRO suffers from low convergence speed and premature convergence. and easily traps in the local optimum. when solving very complex function optimization problems. https://oidwnfm8puvv.aioblogs.com/87843270/partner-selection-and-the-division-of-surplus-evidence-from-ultimatum-and-dictator-experiments
