摘要：

For approximating the fixed points of enriched nonexpansive mappings in Hilbert spaces, we consider a modified Krasnosel'skii-Mann algorithm for which we prove a strong convergence theorem. We also empirically compare the rate of convergence of the modified Krasnosel'skii-Mann algorithm and of the simple Krasnosel'skii fixed point algorithm. Based on the numerical experiments reported in the paper we conclude that, for the class of enriched nonexpansive mappings, it is more convenient to work with the simple Krasnosel'skii fixed point algorithm than with the modified Krasnosel'skii-Mann algorithm.
