Artificial Intelligence / Unit 4 AI 0192 short lesson, about 20 seconds
Split and Propagate
Captions available
The idea
When propagation stalls with choices still open, split one variable's domain into cases and propagate each case separately — recursing until every domain is a single value.
In practice
Splitting is Unit 2's branching; propagation is this unit's own move; the pair is stronger than either alone.
Where people slip
The split is a case analysis, not a guess — both branches get their own full treatment.
