The focus of the present research is on the issue of patterns compatibility regarding an English letter through the use of a probable research Algorithm called the Artificial Immune Network (AIN(. The research clarifies the algorithm ability in patterns compatibility between the original (ideal) pattern of the letter and the deformed patterns since the Artificial Immune Network (AIN (is good for some tasks that require examples. It applies to the issues that have large (wide) areas and large variables. In addition, it can also be quickly and easily solved as well as it provides a solution that is quite near to the ideal solution of the patterns used, The data base used contain file involves data for each original (ideal) pattern of the English letter, the pattern recognition operation (template matching) provided %94 by using Artificial Immune Network. knowing that we obtain the practical result by using MATLAB 2008.
