  • A full NT-step O(n) infeasible interior-point method for Cartesian P_*(k) –HLCP over symmetric cones using exponential convexity 

    Kheirfam, B.؛ Haghighi, M. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2018-11-01)
    In this paper, by using the exponential convexity property of a barrier function, we propose an infeasible interior-point method for Cartesian P_*(k) horizontal linear complementarity problem over symmetric cones. The ...

  • Stability analysis of impulsive fuzzy differential equations with finite delayed state 

    Naseh, D.؛ Pariz, N.؛ Vahidian Kamyad, A. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2018-11-01)
    In this paper we introduce some stability criteria for impulsive fuzzy system of differential equations with finite delay in states. Firstly, a new comparison principle for fuzzy differential system compared to crisp ...
