WebOptimLib is a lightweight C++ library of numerical optimization methods for nonlinear functions. Features: A C++11/14/17 library of local and global optimization algorithms, as well as root finding techniques. Derivative-free optimization using advanced, parallelized metaheuristic methods. WebIf no finite bounds ( lower=-Inf and upper=Inf) are supplied, optim is used with the method specified by optim.method . Note that optim.method="default" means optim.method="Nelder-Mead" for distributions with at least two parameters and optim.method="BFGS" for distributions with only one parameter.
