"NettetFourier–Motzkin elimination, also known as the FME method, is a mathematical algorithm for eliminating variables from a system of linear inequalities. It can output real solutions. The algorithm is named after Joseph Fourier [1] who proposed the method in 1826 and Theodore Motzkin who re-discovered it in 1936. " - Motzkin's theorem

Motzkin's theorem

NettetMotzkin’s transposition theorem (MTT) [ 1] is a so-called theorem of the alternative (cf. Linear optimization: Theorems of the alternative ). It deals with the question whether or not a given system of linear inequalities has a solution. In the most general case such a system has the form. NettetThe purpose of this paper is to present a generalization of the Farkas lemma with a short algebraic proof. The generalization lies in the fact that we formulate the Farkas lemma in the setting of two vector spaces over a common linearly ordered field where one of the vector spaces is also linearly ordered. At the end of the paper, we mention the key …

NettetThe Sylvester–Gallai theorem in geometry states that every finite set of points in the Euclidean plane has a line that passes through exactly two of the points or a line that passes through all of them.

Nettetwas introduced, and studied, by Agmon [1], and Motzkin and Schoenberg [28]. It is a rather naive approach, as it attempts to solve a system of inequalities by solving one inequality at a time.
