  2. in your lecture, you have told abt np, co-np problem using 3-cnf as example. there, when you say that a problem is np since there exists a soln that can be verifiable for the given problem statement, and it is co-np when no soln exist for the given problem domain.. so we say that both take exponential time.. am i correct?

    Sir plz provide the solutions for GATE 2006-Information Technology Paper.

    In your website,For the below papers,The hyperlink is not able to open,please provide the solution for those also,

    GATE 2012 Computer Science Paper
    GATE 2011 Computer Science Paper
    GATE 2010 Computer Science Paper

    Thanks a lot…….You r great…………..

  4. I think this topic is now removed from GATE syllabus. But anyways, it was nice to watch these lecture. It helped me in my college exams. Thanks.
