MIPIII MIPIIIMixed-Integer Programming
MIPIII is the general purpose mixed-integer optimizer for Ketron's
mathematical programming system, MPSIII.
It is also known as WHIZARD
mip. There is a stand-alone version, a callable library version, OML,
and a version that is integrated into the model management system, DATAFORM.
Mixed-Integer Programming. MIPIII uses the branch-and-bound
algorithm with bound projection; branch-and-cut is also available for use where
appropriate. Discrete variable types recognized are: zero/one (a switch),
bivalent (zero or something else), general integer (pick an integer from a range
of values), semicontinuous (must be zero or greater than a lower bound), SOS1
(pick an activity from a set of alternatives) , and SOS2 (piecewise
linearization of a curve).
Extensive user guidance is possible through priority list, starting integer
solution, and numerous solution control parameters. There is a wide choice of
options for branching control and stopping conditions. User controls are
supplied through several convenient means including control tables, command line
arguments, and a GUI front-end.
Input, Output. MIPIII accepts standard MPS format with
mixed-integer markers. A more efficient MPSIII proprietary format is available
through DATAFORM and OML. The branching node tree is displayed if requested;
this is helpful when comparing solution strategies.
Platforms. MIPIII runs on Pentium and compatible PC's, many
workstations, and IBM mainframes.
On the PC, a Windows GUI provides a familiar front-end to the optimizers, it is
particularly useful when you are exploring the solution controls for a new or
troublesome model. The GUI gives you access to all of the MIPIII control
parameters.
