(2) Because PS is a dynamic decision-making process [59], the concept of time is introduced by simulating dynamics that reflect the dynamic nature of the selection process. Correspondingly, interactions between rescuers increase, and the relationship between individual and group behaviors is clarified [60]. When rescuers relinquish one path to turn to other paths, this may generate congestion in other paths and increase travel time. This advantage is also missing from the use of ACO in PS.
