the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran
آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولOn the Computational Efficiency of Branch-and-bound Algorithms
The behavior of the number of partial problems T(A) which are decomposed in a branchand-bound algorithm A (T(A) may be taken as a measure for the computational efficiency of A) is investigated in a fairly general setting. The first result is that the mean number f(n) of T(A) when A is applied to problems of size n grows at least as fast as exponentially with n, under relatively mild conditions,...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولA Computational Comparison of Branch and Bound and Outer Approximation Algorithms for Mixed Integer Nonlinear Programs
In this paper we compare the performance of two codes for convex mixed integer nonlinear programs on a number of test problems The rst code uses a branch and bound algorithm The second code is a commer cially available implementation of an outer approximation algorithm The comparison demonstrates that both approaches are generally capable of solving the test problems However there are signi can...
متن کاملParallel Branch-and-Bound Algorithms
1.1. INTRODUCTION In the beginning of the twenty-first century, large unsolved combinatorial optimization problems have been solved exactly. Two impressive cases should be mentioned. First are two instances of the Monde, Transfert) newspapers. This impressive media frenzy reflected the impact of the achievement, which was deemed of the same order of magnitude as the victory of IBMs parallel com...
