Abstract
In this research, we will discuss and derive an alternative CG parameter for a three-term algorithm based on modified Fletcher-Reeves parameter for two terms of CG method and adding another term as an idea to reach the new search direction to satisfy the sufficient descent property leading to the approach and to the minimum point of the function using an inexact line search. On a number of known test functions in order to obtain the best numerical results when compared to the famous techniques of the same type. The algorithm proposed during this research proved its efficiency in both the theoretical and numerical aspects and achieved a global convergence and a sufficient descent condition in a number of basic hypotheses.
