SEARCH, blackbox optimization, and sample complexity
Kargupta, H.; Goldberg, D.E. - 2009
The SEARCH (Search Envisioned As Relation and Class Hierarchizing) framework developed elsewhere (Kargupta, 1995; Kargupta and Goldberg, 1995) offered an alternate perspective toward blackbox optimization -- optimization in presence of little domain knowledge. The SEARCH framework investigates the...

Sequencing and scheduling in flowshops with task redistribution
Burdett, Robert L.; Kozan, Erhan - 2001
In some manufacturing situations, station tasks or operations can be shifted or redistributed to adjacent stations when adjacent stations have the appropriate equipment and the workers on that station can perform the shifted work to a reasonable level of competency. This paper addresses such an...
