vntrs: Variable Neighborhood Trust Region Search
An algorithm for nonlinear global optimization based on the variable neighbourhood trust region search (VNTRS) algorithm proposed by Bierlaire et al. (2009) "A Heuristic for Nonlinear Global Optimization" <doi:10.1287/ijoc.1090.0343>. The algorithm combines variable neighbourhood exploration with a trust-region framework to efficiently search the solution space. It can terminate a local search early if the iterates are converging toward a previously visited local optimum or if further improvement within the current region is unlikely. In addition to global optimization, the algorithm can also be applied to identify multiple local optima.
