RElim 3.54

A program to find frequent item sets (also closed and maximal) with the relim algorithm (recursive elimination), which is inspired by the FP-growth algorithm, but does its work without prefix trees or any other complicated data structures. The main strength of this algorithm is not its speed (although it is not slow, but even outperforms apriori and eclat on some data sets), but the simplicity of its structure. Basically all the work is done in one recursive function of fairly few lines of code.

An extension of the algorithm to mine fuzzy frequent item sets (which is available as part of this program, but was originally implemented as a separate program relx) has been developed in:
