We should state dual LP problem, which should be feasible and unbounded.

WebSub-probability measure. In the mathematical theory of probability and measure, a sub-probability measure is a measure that is closely related to probability measures. While probability measures always assign the value 1 to the underlying set, sub-probability measures assign a value lesser than or equal to 1 to the underlying set. Helly's theorem is a basic result in discrete geometry on the intersection of convex sets. It was discovered by Eduard Helly in 1913, but not published by him until 1923, by which time alternative proofs by Radon (1921) and König (1922) had already appeared. Helly's theorem gave rise to the notion … Meer weergeven Let X1, ..., Xn be a finite collection of convex subsets of R , with n ≥ d + 1. If the intersection of every d + 1 of these sets is nonempty, then the whole collection has a nonempty intersection; that is, Meer weergeven We prove the finite version, using Radon's theorem as in the proof by Radon (1921). The infinite version then follows by the finite intersection property characterization of Meer weergeven For every a > 0 there is some b > 0 such that, if X1, ..., Xn are n convex subsets of R , and at least an a-fraction of (d+1)-tuples of the … Meer weergeven The colorful Helly theorem is an extension of Helly's theorem in which, instead of one collection, there are d+1 collections of convex subsets of R .
