The Team Orienteering Problem: Formulations and Branch-Cut and Price

Marcus Poggi, Henrique Viana & Eduardo Uchoa
The Team Orienteering Problem is a routing problem on a graph with durations associated to the arcs and profits assigned to visiting the vertices. A fixed number of identical vehicles, with a limited total duration for their routes, is given. The total profit gathered by all routes is to be maximized. We devise an extended formulation where edges are indexed by the time they are placed in the route. A new class of inequalities, min...
