[SCIP] How to get the Dual Solution of the cuts added using a constraint handler

[Naga Venkata Chaitanya Gudapati - nagavenkata.gudapati@studio.unibo.it]

Thank you! Now I think I have to figure how to get the cuts added by the constraint handler.

Thanks and Regards,
Chaitanya

Dear Naga,

you can access the dual solution of a SCIP_ROW by using
SCIProwGetDualsol(). The method SCIPgetDualsolLinear() is returning the
value of SCIProwGetDualsol() for the row that has been generated by a
linear constraint.

Best,
Benjamin
