PlasmoBenders.jl
PlasmoBenders.jl is a custom decomposition-based solver that exploits the graph structure defined for a Plasmo.jl OptiGraph and applies Benders or Nested Benders Decomposition based on the user-defined structure (i.e., it detects the copmlicating variables based on the graph structure). The algorithm used by PlasmoBenders.jl is outlined in the manuscript Graph-Based Modeling and Decomposition of Hierarchical Optimization Problems. In this way, PlamsoBenders implements these decomposition approaches automatically for the user.
Installation
