KALIS_TIMETABLING

Description
Timetabling propagation type for resource constraints
Type
Integer, read only
Values
1 
Notes
This constant is passed to the set_resource_attributes function to specify the kind of propagation to be used for filtering the resource constraint. The KALIS_TIMETABLING filtering algorithm achieves a very simple and fast filtering. Although less powerful than the algorithms KALIS_DISJUNCTIONS (unary resources only) and KALIS_TASK_INTERVALS that may lead to a stronger pruning, the speed of the KALIS_TIMETABLING filtering allows the search process to explore more nodes in the same amount of time which makes the algorithm competitive for simple problems and also for very large problems where the computational overhead of other filtering algorithms is prohibitive.
