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.
Control-flow diagrams were developed in the 1950s, and are widely used in multiple engineering disciplines. They are one of the classic business process modeling methodologies, along with flow charts, drakon-charts, data flow diagrams, functional flow block diagram, Gantt charts, PERT diagrams, and IDEF.

English: A control flow graph of the example function on the cyclomatic complexity page. Date: 19 April 2009: Source: ... Template:Program analysis; Global file usage.
An example control-flow graph, fully converted to SSA. Now, the last block can simply use y 3, and the correct value will be obtained either way. A Φ function for x is not needed: only one version of x, namely x 2 is reaching this place, so there is no problem (in other words, Φ(x 2,x 2)=x 2). Given an arbitrary control-flow graph, it can be ...
