Given the following non convex function: Introducing McCormick convex envelopes: ; ; Mathematical optimization (alternatively spelled optimisation) or mathematical programming is the selection of a best element, with regard to some criterion, from some set of available alternatives. Convex optimization In mathematics, a quasiconvex function is a real-valued function defined on an interval or on a convex subset of a real vector space such that the inverse image of any set of the form (,) is a convex set.For a function of a single variable, along any stretch of the curve the highest point is one of the endpoints. The method used to solve Equation 5 differs from the unconstrained approach in two significant ways. Combinatorics The sum of two convex functions (for example, L 2 loss + L 1 regularization) is a convex function. In mathematical optimization theory, duality or the duality principle is the principle that optimization problems may be viewed from either of two perspectives, the primal problem or the dual problem.If the primal is a minimization problem then the dual is a maximization problem (and vice versa). f : Sn R with f(X) = logdetX, domf = Sn ++ sum: f1 +f2 convex if f1,f2 convex (extends to innite sums, integrals) composition with ane function: f(Ax+b) is convex if f is convex examples Machine Learning Glossary The negative of a quasiconvex function is said to be quasiconcave.
