Iranian Journal of Mathematical Sciences and Informatics ((IJMSI)) publishes high-quality original research papers on the development of theories and methods for computer and information sciences, the design, implementation, and analysis of algorithms and software tools for mathematical computation and reasoning, and the integration of mathematics and computer science for scientific and engineering applications. By means of integrating the specialty studies of both highly reputed and trainee researches, this international journal aims at seizing and describing the latest information in all branches of pure or applied mathematics with special encouragement to researchers in theoretical computer science and mathematical Informatics, for example: Informatics engineering, Information technology (the study, design, development, implementation, support, or management of computer-based information systems), Archival informatics, Bioinformatics, Bioimage informatics, Community informatics, Computational informatics, Development informatics, Disease informatics, Engineering Informatics, Technical informatics and Translational research informatics. Also the following subject can be consider : Discrete Optimization, Algebra, Linear and Nonlinear Programming, Theory of Computation (Computational Complexity, Automata and Formal Languages), Analysis, Control Theory, Theory of Algorithms, Computational Logic, Combinatorics, Coding Theory, Geometry, Cryptographics, Fuzzy Theory with applications, Differential Equations with applications. We are committed to both fast publication and careful refereeing.
