time complexity, which implies 10^64 for 50cities. This is practically useless.Other approaches attempted at solving the problem includeDynamic Programming, branch and bound, linear programming.None of them were feasible for number of c...

We analyze two classic variants of the Traveling Salesman Problem using the toolkit of fine-grained complexity. Our first set of results is motivated by the Bitonic tsp problem: given a set of n points in the plane, compute a shortest tour consisting of two monotone chains. It is a classic...
There is an algorithm which, for every outbranching sequence δ, finds a minimum cost outbranching among all outbranchings with outdegree sequence δ and runs in time ⁎O⁎(4n). We prove Lemma 5.1 by using dynamic programming (DP). However, it will be convenient to present the DP as...

Both brute force and dynamic programming, on the other hand, take roughly constant time (for a fixed n) at each iteration. This fact can be exploited by using our procedure within an iterated local search strategy which, instead of starting each time from a random tour, starts from a ...
Problems in this class can be solved by dynamic programming in time linear in n, though exponential in k: Theorem 1.1 (Balas 1996)Any TSP with condition(1) can be solved in time O(k22k−2n).2 So for(xed k)we have a linear-time algorithm for solving TSPs—whether symmetric or asym...
The best known exact dynamic programming algorithm for the TSP has a complexity of\(O(2^{n}n^{2})\), making it infeasible to scale up to large instances (e.g., 40 nodes). Nevertheless, state of the art TSP solvers, thanks to handcrafted heuristics that describe how to navigate the...
