What are the methods for solving convex optimization problems?
Algorithms for Convex Optimization
Gradient Descent.Mirror Descent.Multiplicative Weight Update Method.Accelerated Gradient Descent.Newton's Method.Interior Point Methods.Cutting Plane and Ellipsoid Methods.Therefore, every optimization problem has a well-defined optimal value.
But not every optimiza- tion problem has an optimal solution.
For example, consider the optimization problem min {ex : x ∈ R}. this problem has an optimal value of zero, but there is no optimal solution.
What are the conditions for a convex optimization problem?
A convex optimization problem is a problem where all of the constraints are convex functions, and the objective is a convex function if minimizing, or a concave function if maximizing.
Linear functions are convex, so linear programming problems are convex problems.
Does convex optimization have unique solution?
Obviously, a strong solution is a unique solution for convex optimization problems.
The opposite implication is not true in general.18 jan. 2024
