lbfgsb

An open source library for the GPU-implementation of L-BFGS-B algorithm

Julia wrapper for L-BFGS-B Nonlinear Optimization Code

Linear regression with the LBFGSB (Limited-memory Broyden-Fletcher-Goldfarb-Shanno BFGS) solver method is a numerical optimization method used to find the minimum of an objective function. It is a gradient descent algorithm that uses an approximation of the Hessian matrix to minimize the function.

a dll wrapper for lbfgsb to be called from python using ctypes library

Hybrid metaheuristic and gradient-based solver for the Electric Capacitated Travelling Salesman Problem (EC‑TSP). Implements random‑keys PSO with a smooth, analytically-differentiable surrogate and periodic L‑BFGS‑B refinement; includes data generation, instance loader, experiments and report generation for e‑cargo bike delivery instances.
