Subject aims expressed by acquired skills and competences

The basic outcome will be the ability to write simple algorithms using a functional style of programing. More precisely, students will understand recursion and recursive data structures, they will be able to use high-order functions, and they will be able to define functions using the pattern matching. They will be able to use functional encapsulation mechanisms such as closures and modular interfaces and correctly reason about variables and lexical scope in programs. On practical level, they will be able to write these basic algorithms in programming language Haskell. Moreover, they will be able to recognize functional style of programming, they will understand advantages and disadvantages of this style of programming and they will be able to compare this style of programming with other approaches like imperative or object-oriented programming.

Teaching methods

Individual consultations
Project work


The course introduces the functional style of programming. It covers basic properties of the functional programming like: the side effect-free programming, functions as first-class values, high-order functions, recursion, pattern matching, or function closures. Also, course introduces selected data structures like a list and a tree and a functional style of working with these structures. As a programming language, Haskell will be used. It is a pure functional, statically typed, lazy evaluated language.

Way of continuous check of knowledge in the course of semester

During the exercise, students will be programing assigned tasks. The results of these tasks will be the crucial part of the final evaluation. At least seven evaluated tasks will be given. It will be possible to get approximately 70 points for these tasks. Additionally, two smaller projects will be given. It will be possible to get remaining points for them.
