An objective vector v of a face Q of a polyhedron P is vector such that Q = {p in P | v*p = max over P} i.e. it is the face on which v attains its maximum.
i1 : P = hypercube 3 o1 = P o1 : Polyhedron |
i2 : Q = convexHull matrix {{1,1,-1,-1},{1,-1,1,-1},{1,1,1,1}} o2 = Q o2 : Polyhedron |
i3 : v = objectiveVector(P,Q) o3 = | 0 | | 0 | | 1 | 3 1 o3 : Matrix QQ <--- QQ |
Since it is the face on which v attains its maximum it can be recovered with maxFace:
i4 : Q == maxFace(v,P) o4 = true |
The object objectiveVector is a method function.
