What heuristics can be used to minimize the asymptotic matrix bandwidth of a 5-point Laplacian discretization?
I can see that there are multiple heuristics to acheive a matrix with minimum bandwidth. As heuristics, they can't guarantee an optimal solution in polynomial time (after all, the problem is NP ...
