Scope and purpose After having solved an optimization problem, it is often the case that one still must verify whether the optimal solution satisfies some additional restrictions that are not included in the original model. Such conditions are called "subtle conditions". In the case of subtle ...
One way to find out is to examine the output structure. Get disp(output.absolutegap) 0 The smallness of the absolute gap implies that the solution is either optimal or has a total length that is close to optimal.Related Topics Traveling Salesman Problem: Problem-Based...
The technique does not ensure an optimal solution, however it usually gives good approximations in a reasonable amount of time. This, therefore, would be a good algorithm to try on the traveling salesman problem, one of the most famous NP-hard problems.Akshat Agrawal...

Particle Swarm Optimization best solution. (PSO) algorithm was developed under the inspiration of behavior laws of bird flocks, fish schools and human communities. A lot of algorithms have been proposed to solve TSP [2-7]. Compared with the genetic algorithm, PSO algorithm has high Some of ...
While we are writing, no algorithm has been found capable of finding the solution of the Travelling Salesman Problem in polynomial time. Therefore we cannot say that the problem belongs to the P class, but we cannot even say the opposite because we do not know the necessary algorithm. It ...

An improved particle swarm optimization (IPSO) algorithm is proposed to solve a typical combinatorial optimization problem: traveling salesman problem, which is a well-known NP-complete problem. In the improved algorithm, particles not only adjust its own flying speed according to itself and the bes...
