Paper detail

GPS: A new TSP formulation for its generalizations type QUBO

We propose a new Quadratic Unconstrained Binary Optimization (QUBO) formulation of the Travelling Salesman Problem (TSP), with which we overcame the best formulation of the Vehicle Routing Problem (VRP) in terms of the minimum number of necessary variables. After, we present a detailed study of the constraints subject to the new TSP model and benchmark it with MTZ and native formulations. Finally, we tested whether the correctness of the formulation by entering it into a QUBO problem solver. The solver chosen is a D-Wave\_2000Q6 quantum computer simulator due to the connection between Quantum Annealing and QUBO formulations.
