Hi All,
I have a PlanningEntity that has several planning variables, say A and
B. Now, if A is O then B can be X or Y and when A is P then B can be Y or Z.
I see two routes:
* create a solution property that generates X, Y and Z as alternatives
for B and rely on the score rules to dismiss improper values,
depending on the value of A
* create an entity property that only generates the possible values
for B (i.e. X,Y for A=O and Y,Z for A=P)
What is the best route?
(Alternatively I do not use the constructionHeuristic and just start of
my solution with a randomly (but correct) generated solution)
Regards,
Willem
