Hi all,

i am a student in the final phase of the Milp model which i want to solve.

So, i have a milp model
columns: 46614
integers:  12540 (binary)
rows:        40842
nonzeros:117823

I tried these simple methods
1.
/solver1.loadProblem(numcols, numrows, start, index, value, collb, 
colub, obj, rowlb, rowub);
solver1.initialSolve();
solver1.branchAndBound() ;/
2.
/solver1.loadProblem(numcols, numrows, start, index, value, collb, 
colub, obj, rowlb, rowub);
CbcModel model(solver1);
CbcMain0(model);
const char * argv2[]={"DAS","-solve","-quit"}; /-> _i don't know what 
this do._/
CbcMain1(3,argv2,model);

/Since i am an amateur, can you help me?
What method should i use to solve the model? 1,2 or something else?
Any recommendations?

The 1st takes an hour and stops.
The 2nd takes either 8' or 35' depending on the data.

Your help is much appreciated.

Christos
