This paper deals with operational fixed interval scheduling problems under uncertainty caused by random delays.
The dual problem is maximize −bT u − 1T w subject to AT u − v + w + c = 0 u 0,v 0,w 0, which is equivalent to the Lagrange relaxation problem derived above.
This approach has led to dramatically improved algorithms for a number of important problems in the areas of routing, location, scheduling, assignment and set ...
A problem is relaxed by making its constraints weaker, so that the feasi- ble set is larger, or by approximating the objective function. In the case of a ...
