  2. Cyclomatic complexity - Wikipedia

    en.wikipedia.org/wiki/Cyclomatic_complexity

    If a (connected) control-flow graph is considered a one-dimensional CW complex called , the fundamental group of will be (). The value of n + 1 {\displaystyle n+1} is the cyclomatic complexity. The fundamental group counts how many loops there are through the graph up to homotopy, aligning as expected.

  3. Control-flow graph - Wikipedia

    en.wikipedia.org/wiki/Control-flow_graph

    In computer science, a control-flow graph (CFG) is a representation, using graph notation, of all paths that might be traversed through a program during its execution. The control-flow graph was discovered by Frances E. Allen , [ 1 ] who noted that Reese T. Prosser used boolean connectivity matrices for flow analysis before.

  4. Basis path testing - Wikipedia

    en.wikipedia.org/wiki/Basis_path_testing

    In software engineering, basis path testing, or structured testing, [1] is a white box method for designing test cases.The method analyzes the control-flow graph of a program to find a set of linearly independent paths of execution.

  5. Control-flow analysis - Wikipedia

    en.wikipedia.org/wiki/Control-flow_analysis

    In computer science, control-flow analysis (CFA) is a static-code-analysis technique for determining the control flow of a program. The control flow is expressed as a control-flow graph (CFG). For both functional programming languages and object-oriented programming languages, the term CFA, and elaborations such as k-CFA, refer to specific ...

  6. Control-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Control-flow_diagram

    Example of a "performance seeking" control-flow diagram. [1] A control-flow diagram (CFD) is a diagram to describe the control flow of a business process, process or review. Control-flow diagrams were developed in the 1950s, and are widely used in multiple engineering disciplines.

  7. Dominator (graph theory) - Wikipedia

    en.wikipedia.org/wiki/Dominator_(graph_theory)

    Corresponding dominator tree of the control flow graph. In computer science, a node d of a control-flow graph dominates a node n if every path from the entry node to n must go through d. Notationally, this is written as d dom n (or sometimes d ≫ n). By definition, every node dominates itself. There are a number of related concepts:

  8. Flow graph (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Flow_graph_(mathematics)

    An example of a signal-flow graph Flow graph for three simultaneous equations. The edges incident on each node are colored differently just for emphasis. An example of a flow graph connected to some starting equations is presented. The set of equations should be consistent and linearly independent. An example of such a set is: [2]

  9. Mason's gain formula - Wikipedia

    en.wikipedia.org/wiki/Mason's_gain_formula

    Mason's gain formula (MGF) is a method for finding the transfer function of a linear signal-flow graph (SFG). The formula was derived by Samuel Jefferson Mason, [1] for whom it is named. MGF is an alternate method to finding the transfer function algebraically by labeling each signal, writing down the equation for how that signal depends on ...
