[SCIP] Resolving with a different objective function

[Victor Miller]

I have a MIP which I want to solve a number of times with different
objective functions.  Just trying to change the objective after a
previous solution doesn't work, so how do I do this?  Do I copy the
model, and solve the copy?  If so, is there a standard way of finding
out which variables in the copy correspond to the variable in the
original?
