Witryna12 paź 2024 · An objective function may have a single best solution, referred to as the global optimum of the objective function. Alternatively, the objective function may have many global optima, in which case we may be interested in locating one or all of them. ... Convex Optimization, 2004. Numerical Optimization, 2006. Articles. … WitrynaIf the objective (minimizing a convex function or maximizing a concave function) and other constraints are convex, and the decision variables appear linearly in the semidefinite constraint, then the problem is a convex optimization problem, which in many cases can be solved efficiently by highly refined semidefinite solvers such as …

This will fail if the constraint set is non-convex. Indeed, Rockafellar's 1970 book Convex Analysis defines the term convex function (on …
Witryna12 kwi 2024 · A convex program is either minimizing a convex function or maximizing a concave function over a convex feasible region.
