WebAt the other extreme, for general graphs, integer programming techniques have been applied (e.g., see [4, 9]). In general, it is unlikely that these algorithms can find optimal solutions in polynomial time since the location problems are NP-hard even when restricted to planar graphs of degree 3 with unit edge lengths. Web$\begingroup$ NP-hardness is a category applying to decision problems. Optimization problems cannot be any more NP-hard than cows. If the corresponding problem is NP-hard, then this provides strong evidence that the optimization problem cannot be solved exactly in polynomial time.
