How to get the values of the coefficients in the constraint matrix of an MILP in SCIP C++ interface

Question

I am trying to get the coefficients of a variable in the constraint matrix of an MILP in SCIP. What I had been thinking was to loop through all the constraints that the variables appear in and somehow get the coefficients ( I am not sure how to). But is there a way to get all the coefficients in an std::vector by using any inbuilt functions.

Answer 1

What type of constraints do you have? If all your constraints are linear, you can include cons_linear.h , loop through all constraints and call SCIPconsGetVars and SCIPconsGetVals . This gives you all the variables that appear in your current constraint, as well as the coefficients.

What is it exactly that you want to do with these coefficients?
