Course detail

# Algorithms and Data Structures

The first part of the course is focused on introducing students to the basic concepts: algorithm, time and memory complexity of the algorithm, data container / collection. The second part of the course deals with the concepts: abstract data type: (Vector, Stack, Queue, Set, Tree) and the use of iterators for these data types. In the third part, students will learn about recursive and non-recursive algorithms, sorting and searching algorithms.

Mode of study

Not applicable.

Entry knowledge

Attending BPC-UDP course or similar.

Rules for evaluation and completion of the course

Up to 40 points for the laboratory lectures (2 tests, up to 20 points each). Minimal needed points from laboratory lectures is 15. Up to 60 points for the final examination. Minimal needed points from final examination is 20. The computer exercises is mandatory, the properly excused missed computer exercises can be compensate.

Aims

The aim of the course is to familiar students with basic concepts of algorithm and data structures such as: the concept of algorithm, computational and memory complexity of the algorithm, abstract data type, recursive and non-recursive algorithms, sorting and searching algorithms. The absolvent has knowledge in the following areas: - concepts of abstract data type, time and memory complexity and its estimates, - the concept of recursion, - basic sorting and searching algorithms. The student is able: - analyze the task using a flowchart, - to determine its time and memory complexity for a simple algorithm, - use basic abstract data types (Vector, Stack, Queue, Set, Tree) and use iterators for these data types., - solve the problem using recursive and non-recursive algorithms, - design and implement basic sorting and searching algorithms.
