Hi,

Unfortunately maven does not have the latest jar files of lp_solve and moreover there are binaries that you must setup manually on your pc. Here is how:

• Download Java wrapper: http://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.2.0/
• Install the binary files: http://lpsolve.sourceforge.net/5.5/Java/README.html
• Install the jar on your local Maven repository.

Note that the lp_solve library is not crucial for the framework. It is required only if you use linear programming and at the moment the only algorithm that does is the DEA. Thus, even though it is not recommended, one can remove these classes and the rest of the code will run fine.

Hope this helps.
