Oct 4, 2021 · The scalability of traveling salesperson problem (TSP) algorithms for handling large-scale problem instances has been an open problem for a long time. We arranged a so-called Santa Claus challenge and invited people to submit their algorithms to solve a TSP problem instance that is larger than 1 M nodes given only 1 h of computing time. Therefore, the problem becomes an (n+1)-city symmetric TSP. After solving, just delete dummy point and then the minimum length Hamiltonian path is solved and we can get the TSP path without returning back the start point.
