WebThe global optimization toolbox has the following methods (all of these are gradient-free approaches): patternsearch, pattern search solver for derivative-free optimization, constrained or unconstrained ga, genetic algorithm solver for mixed-integer or continuous-variable optimization, constrained or unconstrained WebFeb 19, 2024 · The goal of this paper is to investigate an approach for derivative-free optimization that has not received sufficient attention in the literature and is yet one of the simplest to implement and parallelize. It consists of computing gradients of a smoothed approximation of the objective function (and constraints), and employing them within …
[1904.11585] Derivative-free optimization methods
WebJan 1, 1997 · This thesis studies derivative-free optimization (DFO), particularly model-based methods and software. These methods are motivated by optimization problems for which it is impossible or ... WebOct 12, 2024 · The distributed Gauss-Newton (DGN) optimization method performs quite efficiently and robustly for history-matching problems with multiple best matches. However, this method is not applicable for generic optimization problems, e.g., life-cycle production optimization or well location optimization. sharon goforth
