  2. 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.

  3. 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.

  5. Control flow - Wikipedia

    en.wikipedia.org/wiki/Control_flow

    In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.

  6. 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 ...

  7. 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.

  8. Program structure tree - Wikipedia

    en.wikipedia.org/wiki/Program_structure_tree

    A program structure tree (PST) is a hierarchical diagram that displays the nesting relationship of single-entry single-exit (SESE) fragments/regions, showing the organization of a computer program. Nodes in this tree represent SESE regions of the program, while edges represent nesting regions. The PST is defined for all control flow graphs.

  9. Sequential function chart - Wikipedia

    en.wikipedia.org/wiki/Sequential_function_chart

    Sequential function chart (SFC) is a visual programming language used for programmable logic controllers (PLCs). It is one of the five languages defined by IEC 61131-3 standard. The SFC standard is defined as Preparation of function charts for control systems , and was based on GRAFCET [ fr ] (itself based on binary Petri nets [ 1 ] [ 2 ] ).
