Testing Classical and Hybrid Quantum Solvers for Special and Euclidean Traveling Salesman Problem Instances

Abstract
A classical algorithm is tested against D-Wave hybrid quantum annealers for special cases of the Traveling Salesman Problem where the weights of the edges in a graph form an arithmetic progression. The classical algorithm, Christofides, Nearest Neighbor, Simulated Annealing, Ant Colony Optimization, Genetic Algorithm, and D-Wave hybrid quantum annealers are also tested on the Euclidean Traveling Salesman Problem. D-Wave never outperformed the classical algorithm within its specified scope but outperformed all classical algorithms and heuristics for the Euclidean Traveling Salesman Problem before being overtaken at larger problem sizes.
