"WebThis 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 constraints, which are known to be particularly difficult to articulate within the QUBO … " - Tsptw

WebMay 31, 2024 · Theorem 1 allows to solve (P ̲) by solving a simpler (yet NP-hard) Asymmetric TSPTW (P ̲ ̲). A lower bound on z (c ⋆) is then determined as z ̲ (c ̲ ̲ ⋆). As a result, the time-dependent Asymmetric TSPTW (P) can be solved as a (time-invariant) Asymmetric TSPTW, if condition Δ = 1 holds. Theorem 2
