本视频内容介绍了程序的 Cyclomatic Complexity(循环复杂度),一种用于衡量程序复杂度的重要指标。复杂度评估关键在于统计程序中独立执行路径的数量。初始部分讲解了复杂度计算的思路;接着利用控制流图(Control Flow Graph)进行了详实的实操演示。视频通过数学视角解释
4.2.1 Cyclomatic Complexity The measurement of cyclomatic complexity depends on the program's Control Flow Graph (CFG). A CFG uses graphical notations to model the control flow of a program. Nodes in a CFG represent execution commands while edges in a CFG indicate the direction of program execu...
The formula to calculate cyclomatic complexity is relatively straightforward. Start by observing the program’s control-flow graph—a graphical representation of all paths that might be traversed through a program during its execution. Control-flow graph examples of simple programming scenarios (a) if-...
So, the cyclomatic complexity for this code is 3. Hope you now have a clear understanding of how to calculate cyclomatic complexity using the control flow graph (CFG). Next, you will learn where cyclomatic complexity can be applied and its significance in software development. Where Is Cyclomat...
其control flow graph如下: ┌───────────────────────────────────┐ │ getstatic System.out │ │ ldc "Hello World" │ │ invokevirtual PrintStream.println │ │ return │ └──────────────────────────────────...
Use the following formula to calculate cyclomatic complexity (CYC): CYC = E – N + 2P In this equation: P = Number of disconnected parts of the flow graph (e.g. a calling program and a subroutine) E = Number of edges (transfers of control) ...
In this work, we present a Control Flow Graph to apply Cyclomatic Complexity for analyzing smart contracts. Our approach uses EtiIR framework, for creating a CFG from an Etherium Virtual Machine smart contract.Agarwal, ShantanuNational Institute of TechnologyGodboley, Sangharatna...
So the Cyclomatic Complexity = N~E+2 = (14-15) +2 = 3 How can Testers use it? In real world, Testers can sit with developers to derive the control flow graph for a given piece of code. And once we have the graph, we can derive the complexity using this formula. But the story...
The cyclomatic complexity is M=2M=2 Look at the diagram: The control-flow graph of an if...else statement. M=4−4+2⋅1=2M=4−4+2⋅1=2 In a while loop, we can identify the starting node (a condition), a set of instructions to be executed in the loop, and an exit ...
The Stateflow design cyclomatic complexity is equal to the sum of the number of graphical Stateflow decisions, plus the number of MATLAB code decisions in the Stateflow component, plus one (for the default path). In this case, the Stateflow design cyclomatic complexity is calculated as6 + 0...
