[SCIP] Question about "type" of MIPLIB instances

[Wang, Tony Congqian]

Hello community,


I have used SCIP on the MIPLIB2017 benchmark set with make test. At the end I noticed that some instances where classified as type "CIP" although every Problem was obviously a MIP. Does this happen when logic or constraints are used by scip? Does this actually make a difference in how the programm works compared to the MIP instances?


Best regards and many thanks,

Tony
