Mosel files for the Mosel-Python comparison blog

Description

Mosel files for the blog post comparing Mosel and Python.

Instructions for running these files:

Extract the data files into the same directory as the Mosel files
To run a single file via the command line, call Mosel and pass the filename followed by "DATA_FILE_PREFIX=" and the first 2 digits of the data file. For example: mosel SparseGrouping_std.mos DATA_FILE_PREFIX=00

Further explanation of this example: See the blog 4 Main Takeaways from Comparing Xpress Mosel and Python for Optimization Models
