 The CELF algorithm extends on Greedy by introducing a _lazy forwarding_ mechanism, which
 prunes a lot of nodes from being examined, thereby massively reducing the number of conducted simulations.
-This makes CELF massively faster than Greedy on large networks.
+This makes CELF much faster than Greedy on large networks.
