What is the auxiliary columns in decompose() function? https://github.com/Argonne-National-Laboratory/DSP/blob/8a659f3c3ed29c653d69b40f83dc5a772d65ee37/src/Model/TssModel.cpp#L353

Do you mean auxiliary columns? or non-auxiliary columns?

The auxiliary columns can be used for anything. The only implementation in DSP is that one auxiliary column is create in the dual decomposition with Benders to represent the first-stage objective function.
