CVSROOT: /cvs/ppl Module name: ppl Branch: simplex Changes by: cimino@cs.unipr.it 2005-12-05 14:54:01

Modified files: src : Constraint_System.defs.hh Linear_Expression.defs.hh Makefile.am tests/Polyhedron: Makefile.am Added files: src : LP_Problem.cc LP_Problem.defs.hh LP_Problem.inlines.hh LP_Problem.types.hh tests/Polyhedron: LP_Problem1.cc LP_Problem2.cc

Log message: Added the LP_Problem class to the branch, derived from the simplex.cc code. The class is fully functional, but lacks of some features like `incrementality': in this case the problem is solved from scratch. Added also a couple of tests playing with the class, but other tests are needed. For significant tests a change to the C interface and to the `ppl_lpsol' tool is required. LP_Problem declared `friend class' of `Constraint_System' and `Linear_Expression' to allow compiling.
