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.
