Quantum Annealing of Vehicle Routing Problem with Time, State and Capacity
Hirotaka Irie, Goragot Wongpaisarnsin, Masayoshi Terabe +2
We propose a brand-new formulation of capacitated vehicle routing problem (CVRP) as quadratic unconstrained binary optimization (QUBO). The formulated CVRP is equipped with time-ta…
