RESUMO:

The Traveling Car Renter Salesman Problem, or simply Traveling Car Renter Problem (CaRS), is a generalization of the Traveling Salesman Problem (TSP) where the tour can be decomposed into contiguous paths that are traveled by different rented cars. The objective is to construct a minimal cost Hamiltonian circuit, considering the penalty paid for changing cars in the tour.  This penalty is the cost of returning a car to the city where it was rented. CaRS is classified as an NP-hard problem. This work studies the CaRS version classified as: complete, total, unrestricted, with no repetition, free and symmetric. This research  is focused on hybrid procedures that combine metaheuristics and methods based on Linear Programming (LP). The following methods were investigated: scientific algorithms (ScA), evolutionary algorithms (EA), variable neighborhood descent (VND), adaptive local search (ASLP) and a new variant of ALSP called iterated adaptive local search (IALSP). The following techniques are proposed to deal with CaRS:  ScA+ALSP, EA+IALSP, ScA+IALSP and ScA+VND+IALSP. A mixed integer programming model is proposed for CaRS which was used in the ALSP and IALSP. Non-parametric tests were used to compare the algorithms within a set of instances from the literature.
