This representation of fluents is used in the event calculus, in the fluent calculus, and in the features and fluents logics. Some fluents can be represented as functions in a different way. For example, the position of a box can be represented by a function o n ( b o x , t ) {\displaystyle on(box,t)} whose value is the object the box is ...
The fluent calculus is a formalism for expressing dynamical domains in first-order logic.It is a variant of the situation calculus; the main difference is that situations are considered representations of states.
This is known as the frame rule (named after the frame problem) and enables local reasoning. It says that a program that executes safely in a small state (satisfying P {\displaystyle P} ), can also execute in any bigger state (satisfying P ∗ R {\displaystyle P\ast R} ) and that its execution will not affect the additional part of the state ...

The version of the situation calculus introduced by McCarthy in 1986 differs to the original one by the use of functional fluents (e.g., (,) is a term representing the position of x in the situation s) and for an attempt to use circumscription to replace the frame axioms.
