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,

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 ”metaheuristic search by column generation” (for short, SearchCol).

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.

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

A Column Generation Scheme for Faculty Timetabling
2005In this paper we deal with the problem of building a time-table for the courses of a university faculty. We propose an integer linear programming approach based on column generation. Each column is associated with a weekly timetable of a single course.

SearchCol: Metaheuristic Search by Column Generation
2010We propose a general framework for the combination of column generation (CG) with metaheuristics (MHs) aiming to solve combinatorial optimization problems amenable for decomposition approaches, "SearchCol". The combination of the two approaches is based on representing the solution of the problem as the selection of a subset of solutions of smaller ...

Generation and Testing of Immunoaffinity Columns
2005Immunoaffinity purification is a highly specific, reversible technique that has the potential to be used for the one-step isolation of an analyte from many complex matrices. Application of an immunoaffinity column to isolate and concentrate an analyte may decrease the amount of solvent used, decrease the number of purification steps, shorten analysis ...

In this chapter, we shall discuss the most important computational technique of solving a large linear program. If a linear program has a very large number of columns (variables), perhaps too many to write down, we can use the column generating technique to obtain the optimum solution.
