تعتمد معظم خوارزميات التوقيع الرقمي الحالية في بنيتها على مفاهيم رياضية معقدة
يتطلب تنفيذها وقتاً طويلاً و جيداً حسابياً كبيرا. و كمحاولة للتخفيف من هذه المشاكل
اقترح بعض الباحثون خوارزميات توقيع رقمي تعتمد على توابع و عمليات حسابية بسيطة
سريعة التنفيذ، إلا أن ذلك كان على حساب الأمان.
The majority of recent digital signature algorithms depend, in their
structure, on complicated mathematical concepts that require a long
time and a significant computational effort to be executed. As a
trial to reduce these problems, some researchers have proposed
digital signature algorithms which depend on simple arithmetic
functions and operations that are executed quickly, but that was at
the expense of the security of algorithms.

Multi-objective evolutionary algorithms are used in a wide range
of fields to solve the issues of optimization, which require several
conflicting objectives to be considered together. Basic evolutionary
algorithm algorithms have several drawbacks,
In the Multi-objective Traveling Salesman Problem (moTSP)
simultaneous optimization of more than one objective functions is
required. This paper proposes hybrid algorithm to solve the multiobjectives
Traveling Salesman problem through the integration of
the ant colony optimization algorithm with the Genetic algorithm.
This paper introduces a new algorithm to solve some problems
that data clustering algorithms such as K-Means suffer from.
This new algorithm by itself is able to cluster data without the
need of other clustering algorithms.
Nonlinear conjugate gradient (CG) method holds an important role in solving large-scale unconstrained optimization problems. In this paper, we suggest a new modification of CG coefficient �� that satisfies sufficient descent condition and possesses global convergence property under strong Wolfe line search. The numerical results show that our new method is more efficient compared with other CG formulas tested.
