In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions. The simplex is so-named because it represents the simplest possible polytope in any given dimension. For example, • a 0-dimensional simplex is a point, • a 1-dimensional simplex is a line segment, Webbquestions: Dual simplex method, linear programming simplex method, objective functions, optimal solutions, simplex computer solutions, simplex methods, and simplex preliminaries.
