SIAM Journal on Discrete Mathematics

SIAM Journal on Discrete Mathematics is published by Society for Industrial and Applied Mathematics Publications and is in Zone 2 of Mathematics in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Advanced Graph Theory Research, Limits and Structures in Graph Theory and Complexity and Algorithms in Graphs, together about 44.2% of its articles. Its main subfields are Computational Theory and Mathematics. (generated from OpenAlex topic counts and CAS ranking data)

SIAM Journal on Discrete Mathematics (SIDMA) publishes research papers of exceptional quality in pure and applied discrete mathematics, broadly interpreted. The journal's focus is primarily theoretical rather than empirical, but the editors welcome papers that evolve from or have potential application to real-world problems. Submissions must be clearly written and make a significant contribution. Topics include but are not limited to: properties of and extremal problems for discrete structures combinatorial optimization, including approximation algorithms algebraic and enumerative combinatorics coding and information theory additive, analytic combinatorics and number theory combinatorial matrix theory and spectral graph theory design and analysis of algorithms for discrete structures discrete problems in computational complexity discrete and computational geometry discrete methods in computational biology, and bioinformatics probabilistic methods and randomized algorithms.
