<br>
CBC MIP solver is quicker and can solve difficult MIP problem compare<br>
to current GLPK MIP solver.<br>
<br>
GLPK/MathProg has very good data management, pre and post processing<br>
(i.e. input and output to various formats (database, CVS, etc.), far<br>
better than AMPL.<br>
<br>
CBC solver has "half" support for MathProg, only input at the moment.<br>
<br>
I think it would be better if we would adapt this approach:<br>
<br>
GLPK -> CBC MIP-> GLPK wrapper which uses GLPK to parse a MathProg<br>
model with data files, generates mps file, solve it with CBC, and uses<br>
the post solve features of GLPK/MathProg.<br>
<br>
With CBC solver can be user's friendly and popular :-).<br>
<br>
Gurobi and Cplex have these wrappers for glpsol. I am attaching these<br>
2 files (i.e. wrapper_gurobi.c and 3party_cplex_wrapper.c.<br>
<br>
John and Ted,<br>
<br>
What do you think about this approach of having support for CBC in<br>
glpsol? Is the doable.<br>
<br>
Thanks in advance.<br>
<br>
