Mathematical questions about Algorithms, including the analysis of algorithms, combinatorial algorithms, proofs of correctness, invariants, and semantic analyses. See also (computational-mathematics) and (computational-complexity).

An algorithm is an unambiguous specification of how to solve a class of problems. The study of algorithms is the branch of mathematics that specializes in finding efficient (mostly in the terms of time and space complexity) for various computational problems. It often involves combinatorics, number theory and geometry.

The field also includes data structures, computational models and proofs of lower bounds for certain algorithms.
