Dear cbc List members,
I am trying to solve the following problem (see lp string) with the precompiled binary implementation of cbc from command line with
"cbc LPfile.lp solve solu result.txt"
and save the results to result.txt.
I have read the syntax conventions for the lp format and have tested them but there seems to be something I am missing.
Namely for the problem at hand the solver computes a solution but some of the variables are omitted. See the result.txt string.
I would appreciate it if you could give me a hand with this.
Cheers
Andres Botero
