多柱汉诺塔问题. 引用自wiki百科 多塔汉诺塔问题 在有3个柱子时,所需步数的公式较简单,但对于4个以上柱子的汉诺塔尚未得到通用公式,但有一递归公式(未得到证明,但目前为止没有找到反例): 令为在有k个柱子时,移动n个圆盘到另一柱子上需要的步数,则: 对于任何移动方法,必定会先将个圆盘移动到一个中间柱子上,再将第n到第n-m个圆盘通过剩下的k-1个柱子移到目标柱子上,最后将m个在中间柱子上的圆盘移动到目标柱子上.这样所需的操作步数为. 进行最优化,易得: . #include <bits/st…

题意:给定N(1<= N <=64)个盘子和M(4<= M <= 65)根柱子,问把N个盘子从1号柱子移动到M号柱子所需要的最少步数,并且输出移动过程. 分析:设f[i][j]表示将i个盘通过j个柱子从第一根柱子移动到最后一根柱子所需要的最少次数,f[i][j]的得到的最优移动方案是先将最小的path[i][j]个盘移动到某一根柱子上,然后通过一个dfs输出移动次序. #include <cstdlib> #include <cstring> #includ…

Strange Towers of Hanoi 大体意思是要求\(n\)盘4的的hanoi tower问题. 总所周知,\(n\)盘3塔有递推公式\(d[i]=dp[i-1]*2+1\) 令\(f[i]\)为4塔转移步骤. \(f[i]=min(f[i],f[k]*2+d[i-k])\) 即先以4塔以上面的\(k\),再以3塔移\(i-k\),最后以4塔移动回去. 可以推广到\(n\)盘\(m\)塔 2018.5.26…
