Infeasibility Cutting Plane for Unit Commitment Problem

CSEE Journal of Power and Energy Systems
This paper introduces a new type of cutting plane for the unit commitment (UC) problem, namely “infeasibility cutting plane”. The infeasibility cutting plane refers to a type of logic constraint that eliminates the combination of integer ...

Cutting Force Prediction in Drilling of Titanium Alloy

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
Cutting force in drilling of Ti-6Al-4V is studied with simulation based on a predictive model. In the force model, three-dimensional chip flow is made by piling up the orthogonal cuttings in the planes containing the cutting velocities and the chip flow ...

Cutting Planes in Combinatorics

European Journal of Combinatorics, 1985
The author uses two combinatorial problems: packing diamonds into a Chinese checkerboard nd Deza's proof of a conjecture of Erdős and Lovàsz [\textit{M. Deza}, J. Comb. Theory, Ser. B, 16, 166-167 (1974; Zbl 0263.05007)] to illustrate how Gomory's cutting plane method for solving integer linear programming problems can be used to solve combinatorial ...
