Note: The students in Computer Science curriculum, who started their Bachelor studies in Fall 2015/2016, are allowed to choose one course from MTAT.05.125 Introduction to Theoretical Computer Science and MTAT.06.008 Artificial Intelligence I as a part of the degree requirements. In a case of doubt, please check your eligibility with the study coordinator.
Final Exam
The date and time for the final exam is Thursday, December 21st, 12:00 - 14:00, in Paabel 220 (during the practise session, but we start 15 minutes earlier). The exam will cover the matrial of the last eight weeks (Turing machines and computability theory). Any printed and hand-written material is allowed in the exam. No electronic devices (phones, tablets, calculators, etc.) can be used.
Final exam on December 21st, 2017:
Midterm Exam
Midterm exam on November 2nd, 2017:
Literature
- Michael Sipser, Introduction to the Theory of Computation
- Jiri Matousek and Jaroslav Nesetril, An Invitation to Discrete Mathematics
Course description
This is a bachelor-level introductory course into the theory of computer science. The course will emphasize mathematical foundations of computer science, and will focus on analysis and proofs. The course will not focus on implementations and programming.
In the first few weeks we will briefly cover basic counting techniques in combinatorics. Then, approximately half of the semester will be devoted to the automata theory. The second half of the semester will be devoted to computational models, Turing machines and NP-hardness.
Grading policy
There will be a number of homeworks, the mid-term and final exams. The homeworks and exams are evaluated on the scale 0-100. The final grade is taken as a weighted average of homeworks and exams, and translated into "A"-"F" scale. The composition of the grade is: homeworks (30%), mid-term exam (30%) and final exam (40%). The homeworks will mainly contain questions of theoretical and mathematical nature, and typically will not include programming tasks.
