[SCIP] What is the difference between SCIP_DECL_PROBDELTRANS and SCIP_DECL_PROBDELORI?

[Xiangyong Li]

Dear all,


I am looking at the project "Coloring" in the SCIP.


I saw SCIP_DECL_PROBDELTRANS and SCIP_DECL_PROBDELORI.


I want to know what is the difference between transformed and original problem? Why we need these two problems? Can I just use one?
And is there any document regarding the "problem" managing?


Thanks,


Xiangyong
