FortMP Example

Accessing FortMP Executable Environment: To execute the stand-alone FortMP system and solve this example the following preparations are made.

Preparing the Data File: The input data is placed in a file named ‘MODEL.MPS’.

Preparing the Spec File: A set of control commands known as ‘SPECS controls’ or as ‘SPECS commands’ is placed in a file named ‘FORTMP.SPC’.

No special controls are needed to solve the simple example but the file FORTMP.SPC should contain the following two commands as a minimum:
BEGIN 
*MODEL NAME (testin)
*-------------------
INPUT FILE NAME (filename) 
OUTPUT FILE NAME (filename) 
LOG FILE NAME (filename)

MAXIMIZE 
PRESOLVE ON
FEASIBILITY TOLERANCE = 1.0d-6 
INVERT FREQUENCY = 75
END

Executing FortMP: With this all controls are set to default values and the input and output files are named by default to be,

MODEL.MPS    The input data file in MPS format.
MODEL.RES     The solution output file.

Viewing the Results: With the two input files in place it is only necessary to execute the stand-alone FortMP program in order to solve the problem and obtain the outputs.
