gemseo-bilevel-outer-approximation
Overview
GEMSEO plugin for Bi-Level Outer Approximation.
The implementation is based on the work done by Pierre-Jean Barjoux in:
- Barjhoux, P. J., Diouane, Y., Grihon, S., & Morlier, J. (2022). An outer approximation bi-level framework for mixed categorical structural optimization problems. Structural and Multidisciplinary Optimization, 65(8), 214.
- Barjhoux, P. J., Diouane, Y., Grihon, S., Bettebghor, D., & Morlier, J. (2020). A bi-level methodology for solving large-scale mixed categorical structural optimization. Structural and Multidisciplinary Optimization, 62(1), 337-351.
It contains:
- Benders formulation decomposition
- Bi-level Outer Approximation optimization algorithm to solve mixed integer optimization problems.
- Several strategy of Bi-level Outer Approximation improvements:
- Convexification alpha - underestimator
- Post Optimal Sensitivity Amplification (POSA)
- Adaptive Convexification
- Shape Function Penalization and Hyper-sphere Penalization implementation
- A wrapper of the Open source version of MMA solver.
