Regarding CPLEX warning

[SANKAR MAHESH R]

Hi everyone. I'm Sankar Mahesh, a PhD student from India. I'm using CellNetAnalyzer to analyze genome-scale models as per the ASTHERISC package ( Designing microbial communities to maximize the thermodynamic driving force for the production of chemicals | PLOS Computational Biology ).

When I run simulations through this, I get a warning.

Warning: MILP terminated with status Infeasible.
 
> In max_min_driving_force_pathway_higher_mdf_max_exchanges (line 470)
In CNAcomputeOptMDFpathway_higher_mdf_max_exchanges (line 130)
In astherisc (line 609)
In generateToyModelReport (line 49)
Minimal driving force: -15.42, maximal driving force: 16.42.

The warning states that MILP terminated with status infeasible, but still I get a value at the end of the simulation, as shown above.

I further checked the functions involved and it seems like the function can still retrieve the current best solution from dfs (Attached as an image)

The report that I generated is identical to the one that was shared by the authors.

I want to know if this is a usual thing to get this warning or if I'm missing something. 

Thanks,

Sankar.
