(2009) \"A Heuristic for Nonlinear Global\nOptimization\" . The method combines\nneighborhood exploration with a trust-region framework to\nsearch the solution space efficiently. It can terminate a local\nsearch early when the iterates converge toward a previously\nvisited local optimum or when further improvement within the\ncurrent region is unlikely. The algorithm can also be used to\nidentify multiple local optima.", "URL": "https://loelschlaeger.de/vntrs/", "BugReports": "https://github.com/loelschlaeger/vntrs/issues", "License": "GPL-3",
