[SCIP] Set-partitioning formulation, how to have the heuristics working on the corresponding set-covering formulation ?

[Benjamin Müller]

Dear Xavier,

you could write your own heuristic that uses a separate SCIP that 
contains the Set Covering formulation / relaxation for the current 
variable bounds. After solving this formulation, you need to check 
whether one of the solutions satisfies all of your set partitioning 
equalities and add it to (the main) SCIP.

Best regards,
Benjamin
