Imputing a convex objective function

Imputing a convex objective function. Abstract: We consider an optimizing process (or parametric optimization problem), i.e., an optimization problem that depends on some parameters. We present a method for imputing or estimating the objective function, based on observations of optimal or nearly optimal choices of the variable for several ...

Witryna7 kwi 2024 · The main characteristic of the objective function is that it is a positive definite function (as R l a v e is a positive parameter ∀ l ∈ L multiplied by a sum of two square variables, i.e., P l f + Q l f 2), which implies that it is a strictly convex function that will ensure a global optimal solution with an efficient solution technique . Witryna13 mar 2024 · The concept that delivers results in convex optimization is that the objective function have a convex epigraph, that is, the set of points { ( x, f ( x)): x ∈ constraint set } be convex.
