Course details

Functional and Logic Programming

FLP Acad. year 2023/2024 Summer semester 5 credits

Current academic year

Practical applications and broader introduction into lambda calculus and predicate logic within the context of functional and logic programming languages. Within functional programming, abstract data types are discussed, as well as the use of recursion and induction, manipulation of lists and infinite data structures in language Haskell. Experience in logic programming is gained in programming languages Prolog (cut operator, state space search, database modification), CLP, and Goedel. Moreover, principles of their implementation are mentioned too.

Subject specific learning outcomes and competences

Students will get basic knowledge and practical experience in functional and logic programming (two important representatives of declarative programming). Moreover, they will get basic information about theoretical basis of both paradigms and implementation techniques.
Use and understanding of recursion for expression of algorithms.

Learning objectives

Obtaining a basic knowledge and practical experience in functional and logic programming. Introduction into formal concepts used as a theoretical basis for both paradigms.

Why is the course taught

Purely declarative programming languages are such a phenomenon, which enables to get a new viewpoint on many problems and, thus, one can obtain new, original solutions.

Prerequisite knowledge and skills

Processing (analysis, evaluation/interpretation/compilation) of programming languages, predicate logic.

Syllabus - others, projects and individual work of students

  1. A simple program in Haskell programming language (Hugs, GHC, GHCi).
  2. A simple program in Prolog/Gödel/CLP(R) (SWIPL, Gödel, CiaoProlog).

Progress assessment

  • Mid-term exam, for which there is only one schedule and, thus, there is no possibility to have another trial.
  • Two projects should be solved and delivered in a given date during a term.

Controlled instruction

  • Mid-term exam - written form, questions and exercises to be answered and solved, no possibility to have a second/alternative trial - 20 points.
  • Projects realization - 2 projects, implementation of a simple program according to the given specification - one in a functional programming language the other in a logic programming language - 20 points all projects together.
  • Final exam - written form, questions and exercises to be answered and solved, 2 another corrections trials possible (60 points - the minimal number of points which can be obtained from the final exam is 25, otherwise, no points will be assigned to a student).

Exam prerequisites

At the end of a term, a student should have:

  • at least 7 points from mid-term exam (20 possible),
  • at least 4 points from project on functional programming (12 possible),
  • and at least 3 points from project on logical programming (8 possible).

Plagiarism and not allowed cooperation will cause that involved students are not classified and disciplinary action can be initiated.
