Hi Naga,
Setting the result to SCIP_SEPARATED does not immediately trigger a
round of pricing, rather: the separation callbacks of all constraint
handlers are called (in decreasing priority) and if one sets the result
to SCIP_SEPARATED, then another round of pricing is triggered.
Does that help?
Best,
Ambros
