Lagrangian routing

TīmeklisThe Lagrangian problem can thus be used in place of a linear programming relaxation to provide bounds in a branch and bound algorithm. This approach has led to dramatically improved algorithms for a number of important problems in the areas of routing, location, scheduling, assignment and set covering. This paper is a review of … TīmeklisThe efficiency of the augmented Lagrangian method is demonstrated through computational experiments on large scale instances. In particular, it provides near …
