ILOG CPLEX 11.0 User's Manual > Continuous Optimization > Solving Problems with a Quadratic Objective (QP) > Saving QP Problems

After you enter a QP problem, whether interactively or by reading a formatted file, you can then save the problem in a formatted file. The formats available to you are LP, MPS, and SAV. When you save a QP problem in one of these formats, the quadratic information will also be recorded in the formatted file.
