regulaarst
Regulaarst is a term that can refer to several concepts, primarily in mathematics and computer science, relating to patterns and structures that exhibit regularity or follow defined rules. In mathematics, a "regular" object often possesses symmetry or a consistent structure. For example, a regular polygon has all sides equal and all angles equal. In the context of formal languages and automata theory, a regular expression is a sequence of characters that defines a search pattern, used to match character combinations in strings. These expressions are fundamental to pattern matching and text processing in many programming languages and tools.
The concept of regularity also extends to various mathematical structures. A regular graph, for instance, is
