New coefficient of three-term conjugate gradient method for solving unconstrained optimization problems

Recently, Three-Term Conjugate Gradient (TTCG) has become a research trend for solving unconstrained optimization problems. Unfortunately, the problems arise when the existing TTCG methods could only be used by inexact line search. If exact line search is applied, then the formula of TTCG will be reduced to the standard CG method. Therefore, there is a need to come out with a new coefficient of TTCG method that could be used with exact line...
