Hi John;
I run the same LP model ( mps file ) on the executable CLP in the directory
of (Clp-1.3.3-win32-msvc8) and the CLP project in the directory
\Clp-1.3.3\MSVisualStudio\v6\Clp (where there are some other example
projects), but by using the same command "primals" or "solve" the executable
CLP gets the optimal solution in 762.322 seconds and the CLP project under
MSVisualStudio 6 took 193.912 seconds. Huge speed difference happened to all
the models I tried.
What environment did the CLP executable get compiled and built? I am using
the MS Visual Studio 6 under Windows XP. Will MS Visual Studio 8.0 give the
much faster speed or there are some special settings to the project? I tried
to change the optimization property to "maximize speed" in the project
settings, however it said the project option /ZI and /O2 is incompatible. I
tried some other settings in Debug info, but it said project option /GZ and
/O2 is incompatible.
I would really appreciate your help in getting the same speed as executable
CLP in order to write our own algorithm base on CLP to solve large scale
problems.
I am looking forward to hearing from you.
Thanks again.
