WebThe "Traveling Salesman Problem" is a problem where a person has to travel between "n" cities - but choose the itinerary such that: Each city is visited only once. The total distance traveled is minimized. I have heard that if a modern computer were the solve this problem using "brute force" (i.e. an exact solution) - if there are more than 15 ... WebA brute-force algorithm for TSP runs in O(n!), but the celebrated Held-Karp dynamic-programming algorithm, discovered independently by Held and Karp [14] and Bellman [3], runs in O(2nn2) time. Despite extensive efforts and progress on special cases, it is still open if an exact algorithm for TSP exists with running time O((2 ")npoly(n)).

WebThe brute force approach is inefficient because the number of grid points increases exponentially - the number of grid points to evaluate is Ns ** len(x). Consequently, even with coarse grid spacing, even moderately sized problems can take a long time to run, and/or run into memory limitations.
