Why AI Never Commits Too Early | Plan-Space Planning Explained

State-space search locks in action order too soon. Plan-space planning waits until it has to.

In this video, we show how searching over partial plans — instead of world states — lets AI build flexible, dependency-driven solutions.

You'll learn:
– Why premature ordering creates unnecessary constraints
– What a partial plan actually is: actions, ordering constraints, causal links
– How open goals and threats are detected and repaired
– Why shared resources force ordering — and how the planner discovers this
– The least commitment principle: no unjustified order, ever

Animated in Manim. Built for clarity.

Next: even with the right search direction, how does the planner
know which branch to explore first?
