This package enhances the R Optimization Infrastructure (ROI) package
with the GLPK solver for solving mixed integer linear programming (MILP)
problems as well as all variants/combinations of LP, IP.

Enhances the R Optimization Infrastructure (ROI) package by registering
the free GLPK solver. It allows for solving mixed integer linear programming (MILP)
problems as well as all variants/combinations of LP, IP.

Enhances the R Optimization Infrastructure ('ROI') package by registering
the free 'GLPK' solver. It allows for solving mixed integer linear programming (MILP)
problems as well as all variants/combinations of LP, IP.

Enhances the 'R' Optimization Infrastructure ('ROI') package by registering
the free 'GLPK' solver. It allows for solving mixed integer linear programming ('MILP')
problems as well as all variants/combinations of 'LP', 'IP'.
