A QUBO Model for the Traveling Salesman Problem with Time Windows

open access: yesAlgorithms, 2019
This work focuses on expressing the TSP with Time Windows (TSPTW for short) as a quadratic unconstrained binary optimization (QUBO) problem. The time windows impose time constraints that a feasible solution must satisfy. These take the form of inequality
