2022年9月27日 · 格规约算法有许多，最常见的是 LLL 算法，但 LLL 算法得到的基向量质量不一定完美，可能还需要使用 BKZ 算法进行调整。 虽然说 SVP 是 NP-hard 问题，但当维度较低时，存在 LLL 算法可以在多项式时间内求解 SVP 问题。 SVP 问题可以简化成如下表达式： (14) f ⋅ h ≡ g (mod p) 其中所有变量都为整数， (h, p) 为已知向量，此时需要满足 | | (f, g) | | 的长度较小，使得该向量为这个格的最短向量，即可转换为 SVP 问题求解 (f, p) 向量。 我们构造矩阵 M 为： (15) …

2013年2月5日 · REMARK 5 LLL-reduced bases have many other good properties; some are mentioned in the homework. Claim 1 provides us with an approximation to the SVP problem. Assuming we can generate a d-LLL-reduced basis from our input basis, we can then return b 1 as our answer. For d = 3/4 we obtain a 2(n 1)/2 approximation. In what follows, we describe how ...

接下来，把所有的Node类型改成int类型，然后把结点结构中的成员变量改成全局数组 （例如， u->left 和 u->right 分别改成 left [u] 和 right [u]），除了 char 外，整个程序就没有任何指 针了。

2021年5月3日 · 题意： 输入一棵二叉树，输入形式是给定一个结点值和一个字符串，如果字符串时l，则表示该节点在上一层相邻结点的左边，若是r，则表 示该节点在上一层相邻结点的右边，若没有字符串则表示该节点就是根节点，字符串和节点值用小括号括起来，并且相邻 ...

A procedure definition R=lll defines a new procedure R which effectively means "turn right." The first line of input contains four integers r,c,d and e, where r and c (1 ≤ r,c ≤ 40) are the dimensions of the grid in which Karel lives, d (0 ≤ d ≤ 26) is the number of procedure definitions, and e (1 ≤ e ≤ 10) is the number of programs to be executed.
