10 Facts About Frame problem

The frame problem is the problem of finding adequate collections of axioms for a viable description of a robot environment.

Later, the term acquired a broader meaning in philosophy, where it is formulated as the Frame problem of limiting the beliefs that have to be updated in response to actions.

Frame problem is that specifying only which conditions are changed by the actions does not entail that all other conditions are not changed.

Frame problem is that one such frame axiom is necessary for every pair of action and condition such that the action does not affect the condition.

In other words, the problem is that of formalizing a dynamical domain without explicitly specifying the frame axioms.

Solution proposed by McCarthy to solve this problem involves assuming that a minimal amount of condition changes have occurred; this solution is formalized using the framework of circumscription.

Solution to the frame problem given in the fluent calculus is to specify the effects of actions by stating how a term representing the state changes when the action is executed.

Frame problem can be thought of as the problem of formalizing the principle that, by default, "everything is presumed to remain in the state in which it is".

Frame problem rule allows descriptions of arbitrary memory outside the footprint of the code to be added to a specification: this enables the initial specification to concentrate only on the footprint.

Since domains are expressed in these languages rather than directly in logic, the frame problem only arises when a specification given in an action description logic is to be translated into logic.
