Description
Hi there,
my problem has quite a lot of SOS of type 1 (mutually exclusive), and when I save it (CBC solver) in LP format it doesn't create a SOS section.
Here is a link with reference to that SOS section: https://www.ibm.com/support/knowledgecenter/SSSA5P_12.10.0/ilog.odms.cplex.help/CPLEX/FileFormats/topics/LP_MIP.html
I haven't looked at the CBC code yet, might this be an issue with python-mip or is it for sure a CBC issue?
