Compatibility to DRMSMIP

1

Changed type definitions to allow DR functions

and update example

Handling the case when the subproblem is unbounded

10

Conditioned when the coupling variables are free, e.g., during the temporal decomposition

Handle dual infeasible subproblem in DwBundleDual (Issue211)

2

The original implementation did not add cuts when at least one of the subproblems was dual infeasible. This is fixed to generate columns using extreme rays.

Bug in loading large number

1

Example: https://github.com/Argonne-National-Laboratory/DSP/blob/master/examples/cpp/farmer.cpp#L69 When the upper bound is set to `1e+20`, the finite lower bound (e.g. `200`, `240`) is ignored. Solver: Gurobi 9.1.2

Patch for Subgradient method

2

For DD/DdMasterSubgrad: Changed the part where the lagrangian was used for the subproblem objective coefficient instead of the sum of the original objective and lagrangian.

As mentioned in #54, there is no standard way to access the subproblem solutions once the algorithm is terminated. This code saves the solutions in LD.

The type for `primal_solution` is supposed to be `Dict{Any, Float64}` instead of `Dict{Int, Float64}`, to allow general coupling_id types. This happens when the coupling ID is set to `'y'`, for...
