Heuristic and exact algorithms for generating homogenous constrained three-staged cutting patterns
An approach is proposed for generating homogenous three-staged cutting patterns for the constrained two-dimensional guillotinecutting problems of rectangles. It is based on branch...

Extreme point characterizations for infinite network flow problems
We study capacitated network flow problems with supplies and demands defined on a countably infinite collection of nodes having finite degree. This class of network flow models in...

Improved Bounds for Speed Scaling in Devices Obeying the Cube-Root Rule
Speed scaling is a power management technique that involves dynamically changing the speed of a processor. This gives rise to dualobjective scheduling problems, where the operating...
