Synopsis:

The course is devoted to incorporation of complexity questions during algorithm development, introduction to NP completeness and generally to complexity classes of deterministic or nondeterministic Turing machines bounded by time or space. Emphasis is placed on mutual relations among these classes. Aside from nondeterministic classes we examine probability classes. Class of interactive protocols is presented at the end of lecture course.

Syllabus of lectures:

1.Complexity dimensions - expected, randomized, amortized; basic data structures 2. Divide &amp; conquer - recurrence, Strassen algorithm, sorting (+lower bound), median algorithm, prune and search 3. Fibonacci heaps, Dijkstra algorithm, minimum spanning tree - Fredman+Tarjan algorithm, Kruskal algorithm and DFU. 4. NP-completeness and basic transforms (SAT, tiling, clique) 5. Further NP complete examples (Hamiltonian paths and cycles, knapsack) Fully polynomial approximation scheme for the knapsack problem 6.
