Problem Space Search Heuristics are local search heuristics based on a very different neighborhood structures. I have had great success on scheduling and partitioning problems.

Robust and Adaptive Scheduling I have worked on finding schedules that perform well in situations where random disruptions are constantly messing everything up.
