invariant state
1State space (controls) — In control engineering, a state space representation is a mathematical model of a physical system as a set of input, output and state variables related by first order differential equations. To abstract from the number of inputs, outputs and… …
2Invariant subspace problem — In the field of mathematics known as functional analysis, one of the most prominent open problems is the invariant subspace problem, sometimes optimistically known as the invariant subspace conjecture. It is the question whether the following… …
3Invariant (computer science) — In computer science, a predicate that, if true, will remain true throughout a specific sequence of operations, is called (an) invariant to that sequence.UseAlthough computer programs are typically mainly specified in terms of what they change, it …
4State machine replication — Introduction from Schneider s 1990 survey: : Distributed software is often structured in terms of clients and services. Each service comprises one or more servers and exports operations that clients invoke by making requests. Although using a… …
5State variable — A state variable is an element of the set of variables that describe the state of a dynamical system.In case of simple mechanical systems, position coordinates and their derivates are typical state variables. Temperature, pressure, internal… …
6State-transition matrix — In control theory, the state transition matrix is a matrix whose product with the state vector x at an initial time t 0 gives x at a later time t. The state transition matrix can be used to obtain the general solution of linear dynamical… …
7invariant section — noun a) Something that must not be removed or modified during redistribution. I had to include the GNU Manfesto as it was included in an invariant section. b) A section that will not vary through changing state …
8Class invariant — This article is about class invariants in computer programming, for use of the term in mathematics, see equivalence class and invariant. In computer programming, specifically object oriented programming, a class invariant is an invariant used to… …
9Loop invariant — In computer science, a loop invariant is an invariant used to prove properties of loops.Specifically in Floyd Hoare logic, the partial correctness of a while loop is governed by the following rule of inference::frac{{Cland I};mathrm{body};{I… …
10Controlled invariant subspace — In control theory, a controlled invariant subspace of the state space representation of some system is a subspace such that, if the state of the system is initially in the subspace, it is possible to control the system so that the state is in the …
