Unique Paper Code: Update Awaited

This course focuses on the study of advanced data structures and algorithms for solving problems efficiently and their theoretical behavior. The course also includes study of network flow algorithms, NP completeness and backtracking.

Learning Outcomes:

At the end of the course, students should be able to:

  • Implement and empirically analyze advanced data-structures like tries, suffix trees.
  • Apply amortized analysis.
  • Develop more sophisticated algorithms using techniques like divide and conquer, dynamic programming, greedy strategy, and augmentation.
  • Prove that certain problems are too hard to admit fast solutions.
  • Develop algorithms using backtracking for the hard problems.
