Imputing a convex objective function

Witryna12 paź 2024 · Define the Objective Function. First, we can define the objective function. In this case, we will use a one-dimensional objective function, specifically x^2 shifted by a small amount away from zero. This is a convex function and was chosen because it is easy to understand and to calculate the first derivative. objective(x) = ( … 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 .
