A three-term derivative-free projection method for
convex constrained monotone equations
Haisong Cao
ABSTRACT: In this work, we propose a three-term derivative-free projection method to solve nonlinear monotone
equations with convex constraints based on the structures of the famous Dai-Yuan (DY) conjugate gradient method
and the three-term conjugate gradient method. The proposed derivative-free method is suitable for solving large-scale
problems due to its simple structure and lower storage requirement. The search direction satisfies the sufficient descent
property independent of any line search. The global convergence is established under some conditions. The preliminary
numerical results indicate that the proposed method is robust and effective.
