辗转相除法, 又名欧几里德算法(Euclidean algorithm)乃求两个正整数之最大公因子的算法。 算法示意图 递归法 int getGcd(int a, int b) { return b == 0 ? a : getGcd(b, a % b); } 示例代码 #include <stdio.h> #include <math.h> int getGcd(int a, int b) { return b == 0 ? a...
摘要: The function LM , which arises in the pinwheel scheduling problem, was previously known to be computable in polynomial time. In this paper we present a practical algorithm to compute LM that runs in linear time.关键词: Real-time scheduling Pinwheel scheduling On-line algorithms Euclid's ...
假设扩展欧几里得算法得到的不定方程k \cdot m+y \cdot m_i=gcd(m,m_i)的解为p,q,那么可以得到k的通解为 k=p \times \frac{a_i-x_0}{gcd(m,m_i)}+\frac{m_i}{gcd(m,m_i)} \times \lambda,\lambda \in \mathbb{Z} \\ 带入x=x_0+k \cdot m就有 \begin{align} x&=x_0+\le...

The minimum, maximum and average number of arithmetic operations both on polynomials and in the ground field are derived. We consider five different algorithms to compute gcd(A 1, A 2) where A 1, A 2∈ Z 2[ x] have degrees m≥n≥0. Compared with the classical Euclidean algorithm that...
We develop a general framework for analysis of algorithms, where the average-case complexity of an algorithm is seen to be related to the analytic behaviour in the complex plane of the set of elementary transformations determined by the algorithms. The methods rely on properties of transfer ...
The implementation of the above algorithm is - public int gcd(int a, int b) { for(int div = minimum(a, b); div >= 1; --div) { if(a % div == 0 && b % div == 0) { return div; } } } Select allOpen in new window ...
