from application polytope
Visualization of the HASSE_DIAGRAM of a polyhedron as a multi-layer graph..
MIN_MAX_FACE(LinearProgram lp)
Illustrate the behavior of a linear objective function on the polytope. Draw the filters of the MAXIMAL_FACE and MINIMAL_FACE in distinct colors.
LinearProgram lp: a LinearProgram object attached to the polytope
Color min: minimal face decoration (default: yellow border and ingoing edges)
Color max: maximal face decoration (default: red border and ingoing edges)
