The tortoise arrives at the loop on iteration $\mu$.Since the hare moves faster, it is already in the loop. From the hare's perspective, the tortoise is now some distance ahead of it, and that distance is certainly less than $\lambda$.. Since the hare gets one step closer to the tortoise on each …
WebMay 6, 2013 · So, there's a cycle, and the hare enters it, running around like crazy. Eventually, the tortoise reaches the first node of the cycle. From this point on, both necessarily stay in the cycle: the only way they can go from a node is to the next node, which eventually leads back to the first node of the cycle. In Classical times the story was annexed to a philosophical problem by Zeno of Elea in one of many demonstrations that movement is impossible to define satisfactorily. The second of Zeno's paradoxes is that of Achilles and the Tortoise, in which the hero gives the Tortoise a head start in a race. The argument attempts to show that even though Achilles runs faster than the Tortoise, he will never catch up with her because, when Achilles reaches the point at which the Tortoise start…
