About the course

The course gives a comprehensive foundation for theory, methods and algorithms of mathematical optimization. The prerequisites are linear algebra and calculus.

Lecturer: Oleg Khamisov

The course will cover:
1.One-dimensional optimization: unimodal functions, convex and quasiconvex functions, zero and first-order methods, local and global minima.
2.Existence of solutions: continuous and lower semicontinuous functions, coercive functions, Weierstrass theorem, unique and nonunique solutions.
2.Linear optimization: primal and dual linear optimization problems, the simplex methods, interior-point methods, post-optimal analysis.
4.Theory of optimality conditions: Fermat principle, the Hessian matrix, positive and negative semidefinite matrices, the Lagrange function and Lagrange multipliers, the Karush-Kuhn-Tucker conditions, regularity, complementarity constraints, stationary points.
5.First-order optimization methods: the steepest descent method, conjugate directions, gradient-based methods.
6.Second order optimization methods: Newton's method and modifications, trust-region methods.
7.Convex optimization: optimality conditions, duality, subgradients and subdifferential, cutting planes and bundle methods, the complexity of convex optimization.
8.Decomposition: Dantzig-Wolfe decomposition, Benders decomposition, distributed optimization.
9.Conic programming: conic quadratic programming, semidefinite programming, interior point polynomial time methods for conic programming.
10.Nonconvex optimization: weakly and d.c. functions, convex envelopes and underestimators, branch and bound technique.
