See the Bonmin homepage and Getting Started with. IPOPT implements an interior point line search filter method for nonlinear programming models which functions can be nonconvex, but should be twice continuously differentiable. Solving Technologies and Solver Backends¶. While a problem-specific approach is more desirable, one may attempt to solve this problem by a global optimization solver in Julia such as Couenne or Bonmin, both of which are open-source solvers. The resulting mixed-integer, non-linear programming models (MINLPs) are solved by the BONMIN solver. Bonmin is a hybrid between two classical algorithms for mixed-integer nonlinear programming: an outer-approximation-based branch-and-cut-based algorithm and a pure branch-and-bound algorithm. This paper presents an approach to formulate and solve distribution system VVC and DG units. BONMIN is invoked by using 'bonmin' as solver flag in sdpsettings. Finally keep in mind that your model (as it is right now) is nonconvex and some of the solvers can only give you local optimality guarantees (BONMIN, MindtPy, KNITRO). We solve our model using the Bonmin algorithm available through COIN-OR project on the NEOS Server and examine the optimality of results via constraint and integrality relaxations. Thanks to some awesome continuous integration providers (AppVeyor, Azure Pipelines, CircleCI and TravisCI), each repository, also known as a feedstock, automatically builds its own recipe in a clean and repeatable way on Windows, Linux and OSX.
