Algorithms Research

Algorithms Research is an international peer-reviewed journal which presents papers on algorithms that are inherently discrete and finite and that have some natural mathematical content, either in their objective or in their analysis. The journal features new algorithms and data structures, new analyses or comparisons of known algorithms, complexity studies, and sharply focused review articles of subject areas that are currently active.
