GOAL Stack & Hierarchical Planning

GOAL Stack V/S Hierarchical Planning

What is Goal stack planning?

The reasoning strategy used by STRIPS is goal stack planning. In goal stack planning, the problem solver makes use of a goal stack GS that contains both subgoals and actions that have been proposed to satisfy those subgoals. Goal stack planning uses a stack to hold goals and actions to satisfy the goals, and a knowledge base to hold the current state, action schemas and domain axioms.

What is hierarchical planning?

Planning hierarchies provide a framework for your planning activities in consistent planning and level-by-level planning.
