International Journal of Computer Mathematics (IJCM) is a world-leading journal serving the community of researchers in numerical analysis and scientific computing from academia to industry. IJCM publishes original research papers of high scientific value in fields of computational mathematics with profound applications to science and engineering. IJCM welcomes papers on the analysis and applications of innovative computational strategies as well as those with rigorous explorations of cutting-edge techniques and concerns in computational mathematics. Topics IJCM considers include: Numerical solutions of systems of partial differential equations Theory and computations of non-local modelling and fractional partial differential equations Novel multi-scale modelling and computational strategies Parallel computations Numerical optimization and controls Theory and methods in computational linear algebra Imaging algorithms, deep neural network configurations, and vision restorations General computational stochastic processes Stochastic partial differential equations, Monte Carlo simulations and uncertainty quantification Computational finance and applications Computational medicine, biomedicine and epidemiology Inverse problems and data analysis Mathematical and scientific machine learning, objective-oriented computations Highly vibrant and robust algorithms with applications to modern industries, including but not limited to multi-physics, economics and biomedicine. Papers discussing only variations or combinations of existing methods without significant new computational properties or analysis are not of interest to IJCM. Please note that research in the development of computer systems and theory of computing are not suitable for submission to IJCM. Please instead consider International Journal of Computer Mathematics: Computer Systems Theory (IJCM: CST) for your manuscript. Please note that any papers submitted relating to these fields will be transferred to IJCM:CST. Please ensure you submit your paper to the correct journal to save time reviewing and processing your work. Papers developed from Conference Proceedings Please note that papers developed from conference proceedings or previously published work must contain at least 40% new material and significantly extend or improve upon earlier research in order to be considered for IJCM. Review Articles Review articles on current state of the art research are by invitation from the Editors-in-Chief only. If y
