Determining Condition of state depends on available knowledge. In real world, knowledge availability is always limited, so most of the time, conditions are non-deterministic.

The amount of degree of indeterminacy depends upon the knowledge available.

Four planning strategies are there for handling indeterminacy:

i. Sensorless planning: These kinds of planning are based on any perception. The algorithm ensures that plan should reach its goal at any cost.

ii. Conditional planning: Deals with bounded indeterminacy. Agent makes a plan, evaluate the plan and then execute it fully or partly depending on the condition.

iii. Execution monitoring and replanning: In this kind of planning agent can employ any of the strategy of planning. Additionally it observes the plan execution and if needed, replan it and again executed and observes.

iv. Continuous Planning: It doesn’t stop after performing action. It persist over time and keeps on planning on some predefined events.
