报告内容摘要：In this current presentation, three applicable line search methods are discussed named as 1) merit function, 2) sufficient descent condition and 3) angle condition. Then, these three conditions are applied for relaxed formulation of FORM-based steepest descent search direction. Finally, these line search conditions are compared together through several examples.
