Have you tried to check that by the self service testing team? It is clear that for a more or less exact solution of a one-dimensional minimization problem, it is necessary to perform more computational functions than to satisfy inequalities. The assumptions made suggest that the preferred method of choosing the length of a step associated with checking inequality is more acceptable.
