Many books on Al are available in market but they tend to be dry and formal. I have made this book the most lucid and simplified, that a student feels as if a teacher is sitting behind him and guiding him. The facts and formulae in Al are just the same in all the books, the difference lies in the method of presenting these facts to the students. It can be used as a textbook also for all graduate and postgraduate courses of DU, GGSIPU, JNU, JNTU, UPTU, PTU, RGPV, VTU, GNDU, Nagpur University, Cochin University and many other Indian Universities.
