Write a python script to post-process CBC and CPLEX results

[willu47]

• A results file from CPLEX includes zero values which increases the file size
• Results from CBC often includes very small negative/positive values which should be removed

Write a post-process script which takes a result file and produces a correctly formatted results file with no zero-values or very small values.

This should run on the command line or from a Python script like so:

pp_temba --cplex cplex_results.txt -o cleaned_results.txt
pp_temba --cbc cbc_results.txt -o cleaned_results.txt

from temba.post_process import cplex_results, cbc_results
cplex_results('./cplex_results.txt', './cleaned_results.txt')
cbc_results('./cbc_results.txt', './cleaned_results.txt')

This one-liner works in a bash shell:

sed '/ * 0/d' results.sol > results/cleaned_results.sol # Remove zero value items
