cartesian_products

This library provides predicates for generating and querying Cartesian products over lists. The following categories of predicates are provided:

  • Generation operations - Predicates for generating Cartesian products and tuples.

  • Ordering variants - Predicates that support an additional order argument (default or lexicographic) for controlling output order.

  • Distinct-value generation - Predicates for generating tuples while deduplicating repeated values in factor lists.

  • Indexed access - Predicates for direct access to tuples at specific positions.

  • Lexicographic stepping - Predicates for navigating tuples in lexicographic order.

  • Counting operations - Predicates for counting tuples without generating them.

  • Random selection - Predicates for randomly selecting and sampling tuples.

Dedicated arrangements, permutations, combinations, multisets, derangements, partitions, subsequences, and integer_partitions libraries are also available for focused APIs on related operations.
