算法设计五
- 误差分析的方法有多种，例如，威点逊（J. H. Wilkison）针对的计算机的浮点运算提出的“向后误差分析”，这是一种先验估计误差的方法，较以往的“向前误差分析”在矩阵运算的舍入误差估计上有较好的结果，以而使矩阵的误差分析获得了突破性的进展，使不少用向前误差分析难于判定可靠性的数值方法获得新的进展。-error analysis by a number of means, for example, Granville point Morrison (J. H. Wilkison), refer

- 对电路板的图像进行分割，可以提取电路板中的目标物，以对电路板进行检测。文章使用K均值聚类算法完成对电路板图像的分割，针对传统的K均值聚类算法的不足，提出了使用直方图波形的有效波峰个数来确定K值的大小，并通过使用一种比传统的绝对误差的表示更简洁的表达式，达到了快速分割的目的。对一些电路板图像分割的实验结果表明，文章的方法能够根据目标物的数目有效的确定K值的大小，且比传统的K均值算法减少了运算量及计算时间。-On the circuit board image segmentation, to ex

Improved-algorithm
- 提出一种新的计算 MIE 散射系数的算法。该算法使用了改进的后向递推公式，可对 MIE 系数中的消光系数 Kext 和散射系数 K sca 进行精确计算。由于新算法能显著地减少计算循环次数， 因此明显缩短了计算时间。对广泛运用的递推法和连分式法进行了比较详细的讨论。并且把新算 法的计算结果和已有的成果进行了比较。结果表明：(1)计算的循环次数与粒子的复折射率基本没 有关系；(2)连分式得到的结果通常最准确；(3)新算法在尺度系数较大时(>1000)，计算时间仅为 连分式
