Hello,how to solve NP- completeness problems like travelling salesman problem,finding the minimum set in the given numbers.i need some explanation of how do i guess the solution of that problem??thank u

can u give some example of problem???

You can start up with theoretical approach like,

- Number of cities
- Make the Hamiltonian graph
- Find all possible routes and their values in total.
- Select the minimum Path, which is the shortest path traversing all the cities at least once.
- Using this u will be able to derive an algorithm n continue with it,

…

these problems sometimes have weaker versions that can have a sub-exponential algorithm. sometimes you also don’t want the optimum solution, but an approximate one, or even a probabilistic one. these subproblems are often easier to solve, and scientific papers provide some relatively reliable code for these specific cases.
