建立一套数学模型,模拟计算程序运行时间 Develop an input model, including a definition of the problem size Identify the inner loop Define a cost model that includes operations in the inner loop Determine the frequency of execution of those operations of the given input. 简单的说就是,界定程序的输入...
Big O notation describes the upper bound on the growth rate of an algorithm’s runtime. It provides a way to classify algorithms based on their worst-case performance. For example, an algorithm with a time complexity of O(n) has a linear growth rate, meaning its runtime increases linearly...

This paper shows that the inverse chirp z-transform (ICZT), which generalizes the inverse fast Fourier transform (IFFT) off the unit circle in the complex plane, can also be used with chirp contours that perform partial or multiple revolutions on the uni
Screening programs for colorectal cancer (CRC) often rely on detection of blood in stools, which is unspecific and leads to a large number of colonoscopies of healthy subjects. Painstaking research has led to the identification of a large number of diffe

Algorithm of Reaching Definitions Analysis 首先让所有BB和入口的OUT为空。因为你不知道 BB 中有哪些definition被生成。 当任意 OUT 发生变化,则分析出的definition可能需要继续往下流动,所需要修改各 BB 的 IN 和 OUT。 先处理 IN,然后再根据转移完成更新 OUT。
