In this paper, we introduce a new variant of the bi-objective orienteering problem (BOOP) called the bi-objective orienteering problem with budget constraint (BOOPBC) where an additional constraint is imposed on the budget of the tourist. In this problem, a set of points of interest (POIs) is given each with two profits and an entrance fee. The objective is to design routes visiting a set of POIs,...

This paper proposes an ant colony optimization (ACO) to solve the full-truckload selective multi-depot vehicle routing problem under time windows constraints (denoted by FT-SMDVRPTW). The objective is to construct a solution composed of a set of routes associated with the trucks, aiming at maximizing the total profit. Each order is a pickup and delivery order associated with an origin, a destination,...
