@[Reality_Creator](/user/278629) [oeis](http://oeis.org/A007664) 上好像有题解的做法 , 不过我没找到规律证明 .

OEIS 上是一个根据固定策略算出来的答案

@[zero4338](/user/174469) 这个 oeis 确实有,但是也确实是个 Open Problem 吧……

This leads to the given recursive formula a(n) = min{...}. It follows that the sequence of first differences is A137688 = (1,2,2,4,4,4,...) = 2^A003056(n), which in turn gives the explicit formulas for a(n) as partial sums of A137688. The Frame-Stewart algorithm indeed gives the optimal solution, i.e., the minimal possible number of moves for the case of four pegs [Bousch, 2014]. 看起来是对的
