On three-term conjugate gradient algorithms for unconstrained optimization

This paper presents a project for three-term conjugate gradient algorithms development. The search direction of the algorithms from this class has three terms and is computed as modifications of the classical conjugate gradient algorithms to satisfy both the descent and the conjugacy conditions. An example of three-term conjugate gradient algorithm from this class, as modifications of the classical and well known Hestenes and Stiefel or of the...
