. Starting from the fundamental theory of black-box optimization, the material progresses towards recent advances in structural optimization and stochastic optimization. It relies on rigorous mathematical analysis, but also aims at an intuitive exposition that makes use of visualization where possible. In Section 2, we propose a rst-order accelerated proximal gradient algorithm for this problem. A proximal algorithm is an algorithm for solving a convex optimization problem that uses the proximal operators of the objective terms. . Through an accessible analysis of fundamental problems of hypothesis testing and signal recovery, Anatoli Juditsky and Arkadi Nemirovski show how convex optimization theory can be used to devise and analyze near-optimal statistical inferences. A set B is said to be convex if and only if x , y B , all the points on the line segment connecting x and y also belong to B , i.e., [0 , 1] , x + (1 ) y B . of high-dimensional statistics with optimization. Thus, algorithms solving optimizationproblems are already used online, have been embedded on board, and yet still lack the level of qualication requiredby civil aircraft or manned rocket ight. Recognizing convex Perhaps the simplest algorithm to minimizing a convex function involves the iteration where is a parameter.
