| 摘 要： | 针对传统算法在解决多项式的因式分解过程中,存在着只适用于精确分解而不适合系数为浮点数的多项式的因式分解问题,文中提出一种应用双种群双突变进化策略来对浮点数多项式近似分解的算法,克服了传统算法不能解决浮点数多项式的因式分解的弊端.数值计算结果表明该算法收敛速度快、精度高、稳定性强. |

| Abstract: | The traditional algorithms have the problem in solving polynomials factorization that the algorithms suit to precise factorization,but not to polynomials factorization whose coefficients are float.This paper presents an algorithm which has bi-subgroup and bi-mutation to solving float polynomials approximate factorization by evolution strategies.It overcomes the question that traditional algorithms can't solve polynomials factorization whose coefficients are float.The numerical computation results indicate t... |
