Query: Conjugate Gradients and Accelerated Methods Unified: The Approximate
  Duality Gap View   This note provides a novel, simple analysis of the method of conjugate
gradients for the minimization of convex quadratic functions. In contrast with
standard arguments, our proof is entirely self-contained and does not rely on
the existence of Chebyshev polynomials. Another advantage of our development is
that it clarifies the relation between the method of conjugate gradients and
general accelerated methods for smooth minimization by unifying their analyses
within the framework of the Approximate Duality Gap Technique that was
introduced by the authors.
