This year marks the 70th anniversary of the original paper on the conjugate gradient (CG) method by Hestenes and Stiefel. In honor of this anniversary, we recall the important mathematical properties of CG and present a collection of 10 essential examples that demonstrate the finer points of its mathematical and computational behavior. The goal of these examples is to show the mathematical beauty and hidden intricacies of CG, and to point out some persistent misunderstandings as well as important open problems.
