In this paper, we study the convergence rate of the gradient (or steepestdescent) method with fixed step lengths for finding a stationary point of an$L$-smooth function. We establish a new convergence rate, and show that thebound may be exact in some cases, in particular when all step lengths lie inthe interval $(0,1/L]$. In addition, we derive an optimal step length withrespect to the new bound.

The exact worst-case convergence rate of the gradient method with fixed step lengths for L-smooth functions
