Bounding the gap between the McCormick relaxation and the convex hull for bilinear functions

Mathematical programming, 2015
We investigate how well the graph of a bilinear function $$b{:}\;[0,1]^n\rightarrow \mathbb {R}$$b:[0,1]n→R can be approximated by its McCormick relaxation.

L-CONVEX SYSTEMS AND THE CATEGORICAL ISOMORPHISM TO SCOTT-HULL OPERATORS

, 2017
The concepts of $L$-convex systems and Scott-hull spaces are proposed on frame-valued setting. Also, we establish the categorical isomorphism between  $L$-convex systems and Scott-hull spaces.

The restricted hull operator of M-fuzzifying convex structures

Journal of Intelligent & Fuzzy Systems, 2015
In this paper, the notion of M-fuzzifying restricted hull operators is introduced and several equivalent characterizations are given. It is shown that there is a one-to-one correspondence between M-fuzzifying restricted hull operators and M-fuzzifying ...

Recognition of Handwritten Bangla Basic Characters and Digits using Convex Hull based Feature Set

arXiv.org, 2014
In dealing with the problem of recognition of handwritten character patterns of varying shapes and sizes, selection of a proper feature set is important to achieve high recognition performance. The current research aims to evaluate the performance of the

Convex Hull Extensions

1998
The h-principle. Let p: X: → V be a smooth bundle, q-dimensional fibers, over a smooth n-dimensional manifold V, n ≥ 1; s : X (r) → V is the source map.

Computation of Convex Hulls

2013
When referring to “computation of convex hulls” we understand this as the task of computing the \(\mathcal {H}\)-representation of the convex hull of a given finite point set V⊆ℝ n . Depending on the desired application, one might also need to compute all faces, a description of the face lattice or other geometric information.

Convex Hulls in the Plane

2011
Convex hulls in the plane are examples for shortest paths around sets of points, or around simple polygons. Possibly these paths may be constrained by available polygonal regions. This chapter explains a few exact algorithms in this area which run typically in linear or (nlogn)-time with respect to a given input parameter n. However, the problems could
