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 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" (Leibniz, "An Introduction to a Secret Encyclopædia", c. 1679).
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.
The frame problem is solved by asserting that the situation after the execution of an action is identical to the one before but for the conditions changed by the action. For example, the action of moving the box from the table to the floor is formalized as:
The event calculus is a logical theory for representing and reasoning about events and about the way in which they change the state of some real or artificial world. It deals both with action events, which are performed by agents, and with external events, which are outside the control of any agent.
Fluent Design System (codenamed "Project Neon"), [11] officially unveiled as Microsoft Fluent Design System, [12] is a design language developed in 2017 by Microsoft.Fluent Design is a revamp of Microsoft Design Language 2 (sometimes erroneously known as "Metro", the codename of Microsoft Design Language 1) that includes guidelines for the designs and interactions used within software designed ...
The frame problem shows in this example as the problem that is not a consequence of the above formulae, while the door is supposed to stay closed until the action of opening it is performed. Circumscription can be used to this aim by defining new variables c h a n g e _ o p e n t {\displaystyle change\_open_{t}} to model changes and then ...
The time is measured from the end of the frame check sequence of one frame to the start of the preamble for the next. [ 2 ] : 5 During data reception, some interpacket gaps may be smaller due to variable network delays, clock tolerances (all speeds), and the presence of repeaters (10 Mbit/s only).
