GINO
General Interactive Optimizer
GINO is a powerful tool to solve nonlinear optimization problems
and nonlinear systems of equations. GINO's capability to "maximize
or minimize" is not found in many other equation solvers. This
unique facility can allow you to find solutions that maximize
profit or minimize cost.
With GINO you can be solving nonlinear problems immediately whether
you are a modeling novice or expert. GINO combines a comprehensive
easy-to-use interface with the power of Lasdon and Waren's GRG2
optimizer. GRG2 is an extremely robust state of the art optimizer
that has been used and tested successfully for years on mainframe
computers.
GINO provides you with an interactive environment to set up,
analyze, and solve your models. The program includes over 20
commands for data input, editing, solution, display, and file
handling. On-line help is available for all commands. GINO
recognizes numerous common statistical, financial, and scientific
functions as well.
Problems can be quickly and easily entered from within GINO or
imported from text files created in your word processor. The
following is an example of valid input for GINO (comments are
indicated by a '!'):
! A microcomputer box design model:
MODEL
! For heat dissipation surface area must be at least 888
2 * ( HEIGHT * DEPTH + HEIGHT * WIDTH + DEPTH * WIDTH) > 888;
! The "footprint" can't be too large
DEPTH * WIDTH < 252;
! Need at least 1512 cubic inches to store components
HEIGHT * DEPTH * WIDTH > 1512;
! Some aesthetic requirements
HEIGHT / WIDTH > .518; HEIGHT / WIDTH < .718;
! Use minimization capability to minimize the
! per unit cost of the box
MIN = .1 * DEPTH * ( WIDTH + HEIGHT) + .2 * WIDTH * HEIGHT;
END
GINO is available in a variety of sizes solving problems from 50
to 800 variables. GINO runs on MS-DOS PC's and will take advantage
of a math coprocessor, if present, to greatly speed solution times.
Versions of GINO are also available for the Macintosh and most IBM
and Digital mainframe computers. For further information please
