Exact exponential time algorithm
WebAn algorithm that solves a problem in nondeterministic polynomial time can run in polynomial time or exponential time depending on the choices it makes during execution. The nondeterministic algorithms are often used to find an approximation to a solution, when the exact solution would be too costly to obtain using a deterministic one.

Algorithm description and motivation [ edit ] Number the cities 1 , 2 , … , n {\displaystyle 1,2,\ldots ,n} , with 1 {\displaystyle 1} designated arbitrarily as a "starting" city (since the solution to TSP ... WebResults on exact algorithms for EUCLIDEAN TSP—such algorithms are the topic of our paper—are also quite different from those on the general problem. The best known algorithm for the general case runs, as al-ready remarked, in exponential time, and there is no 2o(n) algorithm under the Exponential Time Hypothesis
WebFurthermore, the more generous a time budget the algorithm designer has, the more techniques become available. Especially so if the budget is exponential in the size of the input. Thus, absent complexity-theoretic … WebIn this survey we use the term exact algorithms for algorithms that flnd exact solutions of NP-hard problem (and thus run in exponential time). The design of exact algorithms has a long history dating back to Held and Karp’s paper [42] on the travelling salesman problem in the early sixties. The last years have seen an emerging interest in
