CondorCKD – Implementing an algebraic knowledge discovery system in a functional programming language

We introduce CondorCKD, an implementation of a novel data mining algorithm using the lazy functional programming language Haskell. While functional programming languages are often considered to be applicable to “toy problems ” only, we try to give prove that these languages can of course be used to tackle demanding real-world programming tasks, and that programmers can benefit from the advantages of functional languages without having to pay too high a price with regard to running time and memory consumption. We describe our experiences gained developing with Haskell, including implementation of a graphical user interface and a novel approach to compute the cycles of an undirected graph. 1
