“…The distinctive feature of the problem investigated here is that the two main assumptions highlighted in the previous paragraph are relaxed, hence a more general model is developed for the MmTSP [18, 25]. The paper introduces three new formulations, extending the authors' previous work in [26, 27]. In the first formulation, the starting depots and the number of patrolling robots starting from each depot are not pre‐specified.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
