Aim

The course gives an insight into how the functional programming often offers a possibility to write shorter and easier-to-understand programs than using the traditional imperative or object-oriented approaches.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• have a good understanding of the fundamental principles for functional programming
• understand the practical consequences of the differences in this paradigm relative to traditional programming
• know the common idioms of functional programming
• understand the benefits and the function of an advanced type system

Competences and skills
For a passing grade the student must

• be a fluent reader of program written in Haskell
• be able to utilize the possibilities of the functional paradigm to write Haskell programs in good style
• be able to do type analysis of relatively complex expressions in Haskell

Judgement and approach
For a passing grade the student must

• have learnt to appreciate the role of program code as a communication medium between people

Contents

The philosophy of functional languages. The programming language Haskell. Language constructs and idioms. Higher-order functions. Lazy evaluation and infinite data structures. Monads and monadic computations. Polymorphic type systems and type classes. Type analysis and type inference.

Examination details

Grading scale: TH - (U, 3, 4, 5) - (Fail, Three, Four, Five)
Assessment: Written examination. To qualify for the exam students must have completed the assignments. The final grade of the course is based on the result of the written examination.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
