[Dip] Alternative solver for subproblems

[Jonas Christoffer Villumsen]

Thanks, Matthew!

I forgot to mention that I am using MS Visual Studio.  Is it essentially the same procedure with a config.site file?  And, how can I check which solver is actually used by DIP?

Best regards and happy holidays,
Jonas

When you configure, you need to set the options for the LP and/or IP solver as well as the location of cplex inc and lib dirs.

I do it with a configuration file and have this:
  export CONFIG_SITE=$HOME/config.site-COIN
in my startup script (.bashrc).

Here is my config file for running at Lehigh:
# COIN config.site file for common autotools settings
#use CPLEX
with_lp_solver=cplex
with_ip_solver=cplex

#location of CPLEX
with_cplex_incdir="/usr/local/cplex/include/ilcplex"
with_cplex_lib="-L/usr/local/cplex/lib/x86-64_debian4.0_4.1/static_pic -lcplex -lpthread"

Hi all,

Could anyone give me a hint on how to set up DIP to use CPLEX for solving integer subproblems?
It seems that the OSI-Cplex solver interface is not included in the DIP project.

(I am new to COIN-OR and DIP).

Any help is much appreciated.

Best regards,
Jonas
