karger min cut algorithm in python 2.7

Question

Here is my code for the karger min cut algorithm.. To the best of my knowledge the algorithm i have implemented is right. But I don get the answer right. If someone can check wh

Answer 1

So Karger's algorithm is a `random alogorithm'. That is, each time you run it it produces a solution which is in no way guaranteed to be best. The general approach is to run it lots of times and keep the best solution. For lots of configurations there will be many solutions which are best or approximately best, so you heuristically find a good solution quickly.

As far as I can see, you are only running the algorithms once. Thus the solution is unlikely to be the optimal one. Try running it 100 times in for loop and holding onto the best solution.
