利用集合论与概率论猎兔
Rabbit Hunting using Set Theory and Probability
AI总结：
针对隐形兔子以未知起点和未知固定步长在整数轴上移动的问题，本文提出基于 Cantor 对角线技巧和概率方法的两种有限步命中策略。
摘要：
设想有一只隐形兔子，它起始于数轴上某个未知的整数点 $A$。在每个时间步，它以一个固定但未知的整数步长 $B$ 跳跃。$A$ 和 $B$ 都是固定整数，但它们的值未知。假设你有一把魔法锤，可以在每个时间步投向数轴上的任意整数点。当锤子击中兔子时，它会立即尖叫，表明你已经击中它。现在的问题是设计一种策略，保证你的锤子能在有限多步内击中兔子。我们将给出两种算法来解决这个问题。第一种涉及集合论中的 Cantor 对角线技巧，第二种则是一种概率方法。
英文摘要：
Imagine an invisible rabbit that starts at some unknown integer point $A$ on the number line. At each time step, it hops by a fixed but unknown integer stride $B$. Both $A$ and $B$ are fixed integers, but their values are unknown. Suppose you have a magic hammer that you can throw at any integer point on the number line at each time step. When the hammer strikes the rabbit, it instantly squeals, indicating you have hit it. The problem now is to devise a strategy that guarantees your hammer will hit the rabbit in finitely many steps. We will provide two algorithms to solve this problem. The first involves Cantor's diagonal trick from set theory, and the second is a probabilistic approach.
