In this paper, a method based on clonal selection algorithm (CLONALG) is proposed for null steering of linear antenna arrays by controlling only the positions of selected elements. The CLONALG is a relatively novel population-based evolutionary algorithm inspired by the clonal selection principle of the human immune system. In order to illustrate the accuracy and flexibility of the proposed alg...

Clonal selection algorithms (CSAs) is a special class of immune algorithms (IA), inspired by the clonal selection principle of the human immune system. To improve the algorithm’s ability to perform better, this CSA has been modified by implementing two new concepts called fixed mutation factor and ladder mutation factor. Fixed mutation factor maintains a constant factor throughout the process, ...

The protein structure prediction problem is concerned with predicting the three dimensional native conformation of a protein from the corresponding one dimensional sequence of amino acids. This paper is concerned with solving the protein structure prediction problem on the simple HP lattice model of a protein. Many algorithms and search techniques exist in literature for solving the protein str...

Abstract At present, many cloning selection algorithms have been studied, and improvements made to the cloning, mutation steps. However, there is a lack of research on optimization updating operation The clonal algorithm traditionally updated through random complement antibodies, which blind uncertain process. added antibodies may gather near local optimal solution, resulting in need for more i...
