add_lsymphony_solver  R Documentation 
Specify that the SYMPHONY software should be used to solve a
project prioritization problem()
using the lpsymphony
package. This function can also be used to customize the behavior of the
solver. It requires the lpsymphony package.

SYMPHONY is an opensource integer programming solver that is part of the Computational Infrastructure for Operations Research (COINOR) project, an initiative to promote development of opensource tools for operations research (a field that includes linear programming). The lpsymphony package is distributed through Bioconductor. This functionality is provided because the lpsymphony package may be easier to install to install on Windows and Mac OSX systems than the Rsymphony package.
