Combinatoorilised

Combinatoorilised is a term found in some non-authoritative mathematical writings to refer to phenomena, methods, or objects associated with combinatorics. It is not a standard term in mainstream mathematics, and its exact meaning can vary by author or region. The word appears to be formed by combining “combinatorial” with a suffix pattern common in certain European languages to form adjectives meaning “characteristic of” or “made from.”

Scope and usage: When used, combinatoorilised may denote discrete structures and counting problems typical of combinatorics, such as sets, sequences, graphs, and tilings, as well as the techniques used to analyze them. This includes counting principles (permutations, combinations, partitions), generating functions, recurrence relations, and inclusion-exclusion, as well as problems in graph theory, design theory, and combinatorial optimization.

Relation to other fields: The concept overlaps with discrete mathematics, computer science (algorithm design and analysis), and probability, especially in areas where the focus is on configurations rather than measurements of continuous quantities.

Examples: A text might discuss combinatoorilised colorings of a graph, combinatoorilised tilings of a region, or combinatoorilised counting of sequences with restricted patterns.

References: Because the term is not standard, readers are advised to consult general textbooks on combinatorics and discrete mathematics for foundational methods; usage of the word may appear primarily in regional or informal sources.
