- The problem is given a weighted graph G = (V,E) with positive weights
- for all edges in E, the weight of a vertex v_i in V is defined as the
- sum of the weights of edges incident on v_i. Find a subset S of V, such
- that |S| = K and the graph G' = ((V-S), E') has no vertex whose weight
- is greater than a constant T. E' is E - edges incident on vertices in S.

- I have heuristic solutions for the problem that seem to work well. I wanted
- to make sure that I was not missing the optimum solution if the problem were
- not NP-complete.

- Thanks in advance for your response.
