Gino (General Interactive Optimizer)

GINO combines the advantages of LINDO with the power of Lasdon and Warren's GRG2 (generalized reduced gradient) optimizer. With its help, the user should be able to solve non-linear, constrained optimization problems on a PC, Mac, 386 or mainframe. GINO includes the "minimise or maximise" capability and is available in an student version with complete documentation.
