We present a discrete spectral framework for the sparse or cardinality-constrained solution of a generalized Rayleigh quotient. This NPhard combinatorial optimization problem is c...
The multilevel generalized assignment problem (MGAP) is a variation of the generalized assignment problem, in which agents can execute tasks at different efficiency levels with di...
This paper proposes a general framework for searching large distributed repositories. Examples of such repositories include sites with music/video content, distributed digital lib...
This work provides a generalization of the traditional response surface methodology (RSM) that can be applied to complex, multi-objective simulation studies. These problems involv...
— We present results of a collaboration project, during which parts of General Motors’ north American vehicle supply chain have been modeled and evaluated. A variant of colored...
