Course Syllabus

Abstract

The course is dedicated to the basics of design and analysis of algorithms. It also involves learning advanced algorithms, data structures and basics of the automata theory. The lectures and practical classes are closely inter-related. The lectures are primarily intended to introduce new topics, whereas the practical classes are intended for solving specific problems by coding programs in C++ or Python. Successful completion of “Introduction to Programming” course is the sole prerequisite for being enrolled in this course.

Learning Objectives

• Students will continue to study algorithm design principles.
• Students will elaborate important concepts of computational complexities for problems and algorithms (both exact and heuristic), which are necessary for further learning computational methods, algorithms for big data, algorithms and computational complexity, machine learning, operations research, game theory, and combinatorial optimization.
• Students will study design principles of selected advanced data structures.
• Students will practice efficiently implementing algorithms and data structures as C++ applications.
• Students will concern selected algorithms on strings.
• Students will concern selected graph algorithms.
• Students will study basic concepts on theory of automata.
• Students will learn basic concepts and methods of designing algorithms.
• Students will acquire skills in designing data structures by using C++ or Python.
• Students will learn approaches to analysis of algorithms complexity in terms of time and space.
• Students will improve team-working skills by using collaborative working tools.
• Students will improve self- and peer-review skills.
• Students will improve skills in writing reports and technical documentation, including rapidly changing documentation using wiki and other specific tools.
