Any decreasing cycle-convergence curve is possible for restarted GMRES

Eugene Vecharynski, Julien Langou

Given a matrix order $n$ , a restart parameter $m$ ( $m < n$ ), a decreasing positive sequence $f (0) > f (1) > ... > f (q) \geq 0$ , where $q < n / m$ , it is shown that there exits an $n$ -…
