RElim is 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.
Note that the current version of this program can only find frequent item sets, not association rules.

If you have trouble executing the program on Microsoft Windows, check whether you have the Microsoft Visual C++ Redistributable Packages for Visual Studio 2015 installed, as the library was compiled with Microsoft Visual Studio 2015.

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