Constraint propagation is a method for solving constraint satisfaction problem (CSP). Scheduling problem can be modelled as a CSP. This paper introduces two constraint propagation algorithms for disjunctive scheduling problem, Edge-Finding and Energy-Reasoning, and compares their propagation ability with some examples. It also gives a hybrid algorithm of Edge-Finding and Energy-Reasoning.
