WebDec 21, 2024 · In this paper, we present a derivative-free algorithm based on modified minimal positive base for bound constrained optimization problems. Compared with the derivative-free algorithms based on the maximal 2n positive base, the algorithms based on the minimal \(n+1\) positive base only need at most \(n+1\) function evaluations at … WebI faced a similar question, and in general it is tough in Python world because choosing a derivative-free optimizer requires one to compare scipy.optimize, dlib, ax-platform, …
