Synopsis:

The course covers the basics of efficient algorithm design, data structures, and graph theory, belonging to the core knowledge of every computing curriculum.

It links and partially develops the knowledge from the course BI-DML.21, in which students acquire the knowledge and skills in combinatorics necessary for evaluating the time and space complexity of algorithms. The course also follows up knowledge from BI-MA1.21, the practical usage of asymptotic mathematics, in particular, the asymptotic notation.

Requirements:

Active algorithmic skills for solving basic types of computational tasks, programming skills in C++ (e.g., the level needed for passing BIE-PA1.21 and BIE-PA2.21) , and knowledge of basic notions from mathematical analysis and combinatorics are expected (e.g., by passing BIE-DML.21 a BIE-MA1.21). Students are expected to take the concurrent course BIE-AAG.21 and BIE-MA2.21.

Syllabus of lectures:

1. Motivation, graph definition, important types of graphs, undirected graphs, graph representation, subgraphs.

2. Connectivity, connected components, DFS, directed graphs, trees.

3. Spanning trees, distances in graphs, BFS, topological ordering.

4. Basic sorting algorithms with the quadratic time complexity. Binary heap as a partially ordered structure, HeapSort.

5. Extendable array, amortized complexity. Binomial Heaps.

6. Operations and properties of binary search trees, balancing strategies, and AVL trees.
