Abstract AR
في هذا البحث تم اقتراح طريقة جديدة لصيغة H / S في التدرج المترافق باستخدام نوعين من التحسينات، أولا اشتقاق نموذج غير تربيعي جديد و ثانيا تطبيق خاصية تقليل الخزن لصيغة BFGS.
الطريقة الجديدة تم برهنتها أنها تحقق الشرط الضروري للانحدار و كذلك تحقق خاصية التقارب الشامل.
Abstract EN
In this paper we proposed a new HS type conjugate gradient method by using two kind of modification, first derived a new non-quadratic model second using structure of the memoryless BFGS quasi-Newton method.
The new proposed method always generates a descent condition.
We give a sufficient condition for the global converges of the proposed general method.
Finally, some numerical results are also reported.
