In this article we provide an algorithm, where to escape from a local maximum y of convex function f over D, we (locally) solve piecewise convex maximization max{min{ f (x) − f (y), py(x)} | x ∈ D} with an additional convex function py(·). The last problem can be seen as a strictly convex improvement of the standard cutting plane technique for convex maximization.

Get this from a library! Non-commutative spectral theory for affine function spaces on convex sets. [Erik M Alfsen; Frederic W Shultz]

The method can be generalized to convex programming based on a self-concordant barrier function used to encode the convex set. Any convex optimization problem can be transformed into minimizing (or maximizing) a linear function over a convex set by converting to the epigraph form.

Convex functions 3–13. Positive weighted sum & composition with aﬃne function nonnegative multiple: αf is convex if f is convex, α ≥ 0 sum: f1 +f2 convex if f1,f2 convex (extends to inﬁnite sums, integrals) composition with aﬃne function: f(Ax+b) is convex if f is convex

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Given a convex program with C2 functions and a convex set S of solutions to the problem, we give a second order condition which guarantees that the problem does not have solutions outside of S. This condition is interpreted as a characterization for the quadratic growth of the cost function.

Duality (optimization)'s wiki: 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 . The solution to the dual problem provides a lower bound to the solution of the primal (minimization) problem.

The proximal point mapping is the basis of many optimization techniques for convex functions. By means of variational analysis, the concept of proximal mapping was recently extended to nonconvex functions that are prox-regular and prox-bounded. In such a setting, the proximal point mapping is locally Lipschitz continuous and its set of fixed points coincide with the critical points of the ...

Jul 18, 2018· Dear All, Has anyone here used the Smooth-R function on the PM DRO (or similar DRO) to mill convex or concave radii? The manual that comes with the unit is somewhat difficult to follow. I'm sure it was crystal clear in it's original language.

Concave/Convex End Mills. Convex End Mills and Concave End Mills are used to produce smooth, half round shapes in the workpiece. The convex shank type cutter are designed for milling an inward-curving () half-circle in the workpiece, while the concave shank type cutter is designed to produce an outward-curving (male) half-circle.

In mathematics, a real-valued function defined on an n-dimensional interval is called convex (or convex downward or concave upward) if the line segment between any two points on the graph of the function lies above or on the graph. Equivalently, a function is convex if its epigraph (the set of points on or above the graph of the function) is a convex set. ...

Abstract It is shown that some of the recently proposed orthotropic yield functions obtained through the linear transformation method are homogeneous polynomials. This simple observation has the potential to simplify considerably their implementation into finite element codes.

1 Convex Sets, and Convex Functions Inthis section, we introduce oneofthemostimportantideas inthe theoryofoptimization, that of a convex set. We discuss other ideas which stem from the basic de nition, and in particular, the notion of a convex function which will be important, for example, in describing appropriate constraint sets. 1.1 Convex Sets

The inequalities in the definition of concave and convex functions are weak: such functions may have linear parts, as does the function in the following figure for x > a. x → a f (x) A function that is concave but not strictly concave. A concave function that has no linear parts is said to be strictly concave.
