Control flow has higher weight (that means that control flow edges tend to be more straight).--dag-control: The diamond shape denotes a decision. Autograph: easy control flow for graphs | tensorflow. A CFG is a graphical representation of a program unit. A control flow graph is process oriented. However, the dependence graph does not fully capture the program's control flow. Consys-slides-4-signal-flow-graph. Control Flow Graph (CFG)¶ To analyze or optimize existing code, bytecode provides a ControlFlowGraph class which is a control flow graph (CFG). Don’t stop learning now. All the statements execute in the same order they appear. ... count the number of regions on the graph: 4 no. StatiCFG is a package that can be used to produce control flow graphs (CFGs) for Python 3 programs. Control Flow Graph: In computer science, a control flow graph (CFG) is the graphical representation of control flow or computation during the execution of programs or applications. It can easily encapsulate the information per each basic block. The second technique, discussed in the next chapter, focuses on data flow. The above example shows eligibility criteria of age for voting where if age is 18 or more than 18 so print message "You are eligible for voting" if it is less than 18 then print "You are not eligible for voting." Program for this scenario is written above, and the control flow graph is designed for the testing purpose. 4. ��a0�~��giش~�����U(�=��|k�^����t���L���0,�%Ȱ�a �k�ienf+:�bi�T�1��"�S ����hu�]9]�n\�K:Y��t���,���@œ1�;D��k�(-��iS��7qkm�����Q��.�z��؍�k:��vFG�~�_�VoM�Da��]>�Yߵ�zIC����,R?���m;.؏��'�������٢�����T/QUl�)vͧ��U-����BaR����GJ;���4"�0��3Q��ã\+GboNo���\w���2�g�̳��iMf���9_�w��mkq9.bG�2Q�44=+�r�t�޾)vm�\n�N�E�1�4!���1Ә� �PB��)���*H}�]��7s��^l��[���tC�#�@JL��fUx�8̩1�9}Y�&��0��R�Rn��KIu�� �7�~���4��0�)��t���o� ?e��-�e�H~a��)]�Z^�ǚs��6}���Tm��B�|ZI����,�S�A�.
