“…Schneider, Stenger, and Goeke (2014) Many works relax the full recharging assumption to a partial recharging policy, e.g., (Bruglieri et al 2015, Keskin and C ¸atay 2016, Desaulniers et al 2016, Duman, Taş, and C ¸atay 2021, Ceselli et al 2021. The majority of these articles develop meta-heuristic algorithms to solve the problem, e.g., (Felipe et al 2014, Hiermann et al 2019, Montoya et al 2017, Froger et al 2017, while some of them propose exact methods. The representative work is Desaulniers et al (2016), where the authors investigate four different recharging policies: full recharging plus single/multiple visits to recharging stations and partial recharging plus single/multiple visits to recharging stations.…”
