Variable Neighborhood Trust Region Search

v0.2.0 · Oct 25, 2025 · GPL-3

Description

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.
