Convex optimization problem definition

WebConvex optimization is the problem of minimizing a convex function over convex constraints. It is a class of problems for which there are fast and robust optimization algorithms, both in theory and in practice. Following the pattern for linear optimization, … WebSep 20, 2024 · By some definitions, it seems that a convex integer optimization problem is impossible by definition: the very fact of constraining the variables to integer values removes the convexity of the problem, since for a problem to be convex, both the objective function and the feasible set have to be convex. Other places seem to consider …
