LPsolve with C++

Hi there,

Suppose a large MIP problem runs in MATLAB using lpsolve in Nm seconds.

If the same large MIP problem runs in C (or C++) using lpsolve in Nc
seconds, would one expect Nc << Nm, i.e. is MATLAB using lpsolve very
efficient?

Hi
 
I have not compared Matlab's use of lpsolve with a C version, but have
run Matlab's for moderate size problems and the process times have been
reasonable. As far as I know, all the Matlab arrays are passed as sparse
to the lpsolve wrapper and that, sometime, helps a lot.
 
Cheers,
Reza
