Nov 22, 2024 · A Control Flow Graph (CFG) is the graphical representation of control flow or computation during the execution of programs or applications. Control flow graphs are mostly used in static analysis as well as compiler applications, as they can accurately represent the flow inside a program unit.

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.

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 conceived by Frances E. Allen, [1] who noted that Reese T. Prosser used boolean connectivity matrices for flow analysis before. [2]

Intuitively, a control flow graph is a representation of the different blocks of code in a Python program, and the different paths that the Python interpreter can take through the code. To get a clearer sense of what this means, let’s introduce one foundational definition.

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).

Control Flow Graph (CFG) A control flow graph(CFG), or simply a flow graph, is a directed graph in which: –(i) the nodes are basic blocks; and –(ii) the edges are induced from the possible flow of the program The basic block whose leader is the first intermediate language statement is …

Control-Flow Graphs •Graphical representation of a program •Edges in graph represent control flow: how execution traverses a program •Nodes represent statements 6 x := 0; y := 0; while (n > 0) {if (n % 2 = 0) {x := x + n; y := y + 1;} else {y := y + n; x := x + 1;} n := n - 1;} print(x); x:=x+n y:=y+1 y := 0 n > 0 n%2=0 y:=y+n print(x) n ...

Question 1: how does information flow between the program points before and after an instruction? Question 2: how does information flow between successor and predecessor basic blocks? Q1: what is the effect of instructions? Q2: what is the effect of control flow?

Experiment shows that when comparing with the conventional CFG, the new CFG that drawn by the proposed algorithm can demonstrate more details, states, and data flows. The CFG drawn by the proposed algorithm can also offer strong support for …
