4|04. 分析dp过程中,套了两层for,分别为1->n,1->m,所有时间复杂度为O(NM)。5|05. 源码/* author: keke project name:LCS算法 Time Complexity: O(nm) */ #include<iostream> using namespace std; int dp[1001][1001],a1[2001],a2[2001],n,m; ...
DP which reduces complexity to O(N2 + M) insread of O(N * M) (useable for long+short string) Hunt-Szymanski Algorithm, which is pretty sexy — considering the character layout of strings LCS using four russians method (at least I guess it is called like this) which is also...
In particular, we first devise an efficient algorithm for the traditional LCS problem that runs in O(R log log n + n) time. Then, using this algorithm we devise an algorithm for the CLCS problem having time complexity O(pR log log n + n) in the worst case. Note that, if R = o...
