Abstract AR
في هذا البحث تم تقدير خوارزمية للأمثلية غير المقيدة و التي اختصت بالتقييس غير الخطي للدوال التربيعية المحدبة بشدة و عممت لاتجاهات مترافقة موزعة لتوسيع الدالة التربيعية.
و اشتقت صيغة لخط البحث غير التام و صممت للاستخدام العام.
كما تمت مقارنة هذه الطريقة مع الطرائق السابقة لثماني دوال اختبارية و بأبعاد (2-100) مع صيغ H / S, DX, F / R, P / R.

Abstract EN
An algorithm for unconstrained minimization is proposed which is invariant to a non-linear scaling of a strictly convex quadratic function and which generates mutually conjugate directions for extended quadratic function.
It is derived for inexact line searches and is designed for general use, it compares favorably numerical tests [over eight test functions and dimensionally up to (2-100)] with the H/S, DX, F/R, P/R, and A/B algorithms on which this new algorithm is based].|
