Feature Representations

What are the feature-based representations of the MW and AHM features?
What are the STRIPS representations of the pum and dm actions?

Other Worlds

An agent can carry only one thing at a time. Modify the world representation suitably.
An agent can carry a box, and a box can carry more than one thing at a time. Modify the world suitably.
Show that each of these worlds produce different plans for the same goal.

Given two actions a₁ and a₂, the composite action a₁ ; a₂ is a₁ followed by a₂.
- What is the effects list of a combined action?
- What is the precondition of the combined action?
