Abstract AR
في هذا البحث، تم دراسة طريقة للتدرج المترافق الطيفية لحل مسائل الأمثلية غير المقيدة و التي تمتاز بالانحدار الكافي و التقارب الشامل و باستخدام خطوط بحث غير مضبوطة.
و قد تم استعمال وسيلة استرجاع Fletchre-Reeves في الصيغتين القديمة و الجديدة و كان لذلك أثر كبير في توفير الزمن المطلوب للحل.
و قد أظهرت النتائج العددية فعالية الطريقة المطورة مقارنة بطريقة –FR.
Abstract EN
In this paper, a modified spectral conjugate gradient method for solving unconstrained optimization problems is studied, which has sufficient descent direction and global convergence with an inexact line searches.
The Fletcher-Reeves restarting criterion was employed to the standard and new versions and gave dramatic savings in the computational time.
The Numerical results show that the proposed method is effective by comparing it with the FR-method.
