WebIn modern C++ implementations, there will be no performance penalty for using simple and lean abstractions, such as concrete classes. Fixed-point computation is precisely the … WebDiscrete fixed-point theorem. In discrete mathematics, a discrete fixed-point is a fixed-point for functions defined on finite sets, typically subsets of the integer grid . Discrete fixed-point theorems were developed by Iimura, [1] Murota and Tamura, [2] Chen and Deng [3] and others. Yang [4] provides a survey.

Fixed point, a … A fixed point (sometimes shortened to fixpoint, also known as an invariant point) is a value that does not change under a given transformation. Specifically, in mathematics, a fixed point of a function is an element that is mapped to itself by the function. In physics, the term fixed point can refer to a … See more In algebra, for a group G acting on a set X with a group action $${\displaystyle \cdot }$$, x in X is said to be a fixed point of g if $${\displaystyle g\cdot x=x}$$.

Their … See more A fixed-point theorem is a result saying that at least one fixed point exists, under some general condition. Some authors claim that results of this kind are amongst the most generally useful in mathematics. See more In domain theory, the notion and terminology of fixed points is generalized to a partial order. Let ≤ be a partial order over a set X and let f: X → X be a function over X. Then a … See more In combinatory logic for computer science, a fixed-point combinator is a higher-order function $${\displaystyle {\textsf {fix}}}$$ that returns a fixed point of its argument function, if one exists. Formally, if the function f has one or more fixed points, then See more In many fields, equilibria or stability are fundamental concepts that can be described in terms of fixed points.
