What is planning in artificial intelligence?

The planning in Artificial Intelligence is about the decision making tasks performed by the robots or computer programs to achieve a specific goal.

The execution of planning is about choosing a sequence of actions with a high likelihood to complete the specific task.

Actions are given as logical descriptions of preconditions and effects.

Summary of Planning Problem in AI

Standard planning algorithms assume complete and correct information and deterministic, fully observable environments. Many domains violate this assumption.

Conditional plans allow the agent to sense the world during execution to decide what branch of the plan to follow.

Execution monitoring detects violations of preconditions for successful completion of the plan.

A replanning agent uses execution monitoring and splices in repairs as needed.

A continuous planning agent creates new goals as it goes and reacts in real time.
