Just a follow-up question to the original question (dual values for the
continious values in a mixed integer problem):
So I basically have to solve the problem again but with fixed integer values
taken from the MIP solution. For the java interface this means:
- retrieve the solutions of the integer variables
- delete old problem (MIP)
- create new problem (LP, old integer vars are fixed)
- solve again
Or is there a better way?
Any hints appreciated.
