Web13 sep. 2024 · L-BFGS-B is a deterministic, gradient-based algorithm for finding local minima of smooth, continuous objective functions subject to bounds on each variable. The bounds are optional, so this software also solves unconstrained problems. L-BFGS-B is accurate and efficient for problems of 1000s of variables.
