Abstract

Inspired by the performance estimation problem (PEP) method, this paper optimizes the step size of the first order method of smooth convex minimization that the gradient corresponding to the iteration point satisfies Q-convergence by examining the worst case convergence boundary (i.e. efficiency) of the cost function. This paper introduces a new and effective first-order method called QGM, which has an effective computation form similar to the optimized gradient method (OGM).
