A Convex Optimization Task is an optimization task that accepts a convex function (over convex sets).

**Context:**- It can be solved by a Convex Optimization System (that implements a convex optimization algorithm).

**Convex optimization**, a subfield of mathematical optimization, studies the problem of minimizing convex functions over convex sets. Given a real vector space [math]\displaystyle{ X }[/math] together with a convex, real-valued function [math]\displaystyle{ f:\mathcal{X}\to \mathbb{R} }[/math] defined on a convex subset [math]\displaystyle{ \mathcal{X} }[/math] of [math]\displaystyle{ X }[/math], the problem is to find a point [math]\displaystyle{ x^* }[/math] in [math]\displaystyle{ \mathcal{X} }[/math] for which the number [math]\displaystyle{ f(x) }[/math] is smallest, i.e., a point [math]\displaystyle{ x^* }[/math] such that [math]\displaystyle{ f(x^*) \le f(x) }[/math] for all [math]\displaystyle{ x \in \mathcal{X} }[/math].

- QUOTE: Convex optimization problems arise frequently in many different fields. This book provides a comprehensive introduction to the subject, and shows in detail how such problems can be solved numerically with great efficiency. The book begins with the basic elements of convex sets and functions, and then describes various classes of convex optimization problems. Duality and approximation techniques are then covered, as are statistical estimation techniques. Various geometrical problems are then presented, and there is detailed discussion of unconstrained and constrained minimization problems, and interior-point methods. The focus of the book is on recognizing convex optimization problems and then finding the most appropriate technique for solving them.
