Optimised search heuristic combining valid inequalities and tabu search [PDF]

This paper presents an Optimised Search Heuristic that combines a tabu search method with the verification of violated valid inequalities. The solution delivered by the tabu search is partially destroyed by a randomised greedy procedure, and then the ...

M-matrices satisfy Newton's inequalities

, 2005
Newton's inequalities $c_n^2 \ge c_{n-1}c_{n+1}$ are shown to hold for the normalized coefficients $c_n$ of the characteristic polynomial of any $M$- or inverse $M$-matrix.

Valid inequalities for the single-item capacitated lot sizing problem with step-wise costs [PDF]

This paper presents a new class of valid inequalities for the single-item capacitated lotsizing problem with step-wise production costs (LS-SW). We first provide a survey of different optimization methods proposed to solve LS-SW.

Approximate Packing Circles in a Rectangular Container: Valid Inequalities and Nesting

, 2014
A problem of packing a limited number of unequal circles in a fixed size rectangular container is considered. The aim is to maximize the (weighted) number of circles placed into the container or minimize the waste.

Causal structures from entropic information: geometry and novel scenarios

New Journal of Physics, 2014
Bell's theorem in physics, as well as causal discovery in machine learning, both face the problem of deciding whether observed data is compatible with a presumed causal relationship between the variables (for example, a local hidden variable model ...

Some New Boole-Type Inequalities via Modified Convex Functions with Their Applications and Computational Analysis

Mathematics
In numerical analysis, the Boole’s formula serves as a pivotal tool for approximating definite integrals. The approximation of the definite integrals has a big role in numerical methods for differential equations; in particular, in the finite volume ...
