PPT-2 DFA versus Normal DFA

Pavan Kumar Akulakrishna MTech SERC SR No 060201105112109469 Under Guidance of Prof Deepak Dsouza Fundamental Question Is 2 way DFA more powerful than a one way DFA. The former represents a centralized approach while the latter represents a decentralized approach The centralized IT department suits some organizations better than others However it is becoming increasingly obvious that organizations may often cons Carefully Synchronizing Words.
