Parallel Machine Scheduling by Column Generation [PDF]
Operations Research, 1999 Parallel machine scheduling problems concern the scheduling of njobs on mmachines to minimize some function of the job completion times. If preemption is not allowed, then most problems are not only š¯’©š¯’«-hard, but also very hard from a practical point of view.

Unit Commitment by Column Generation
2016The unit commitment problem is to determine the schedule of power generating units and the generating level of each unit. The decisions involve which units to commit at each time period and at what level to generate power to meet the electricity demand. We consider the heuristic column generation algorithm to solve this problem.

Combining Column Generation and Metaheuristics
2013In this Chapter, we consider the hybridization of column generation (CG) with metaheuristics (MHs) for solving combinatorial optimization problems. We describe a general framework entitled ā€¯metaheuristic search by column generationā€¯ (for short, SearchCol).

Column Generation Methods for Probabilistic Logic
ORSA Journal on Computing, 1991Nilsson recently introduced a rigorous semantic generalization of logic in which the truth values of sentences are probability values. This led to state precisely several basic problems of artificial intelligence, a paradigm of which is probabilistic satisfiability (PSAT): determine, given a set of clauses and probabilities that these clauses are true,

Carbon nanotubes, CNTs, have probably been made in small amounts since the first fires reduced trees and organic material to ashes. It was not until recently, as part of the so-called nano revolution, that we first recognized the existence of these nanotubes. Sumio Iijima, NEC Fundamental Research Laboratory in Japan, first observed carbon nanotubes as
