forget_shared¶

Removes shared commitments for a predicate or a particular proposition. Facts in private beliefs remain unchanged.

<forget_shared predicate="colour"/>
<forget_shared>
  <proposition predicate="means_of_transport" value="train"/>
</forget_shared>

Attributes and children¶

With predicate and no child, all shared propositions for that predicate are forgotten. Alternatively, provide one proposition child to forget a particular value. Use one form at a time.

Placement and examples¶

Can appear in a plan, postplan, or conditional branch. To clear all shared colour values while retaining any private beliefs about colour:

<forget_shared predicate="colour"/>

For a single value, use the child form above. Use forget to remove a fact from both private beliefs and shared commitments.
