Simple Combinatorial Association Rule Finder

Please read the usage manual first!

SCARF is a free program and online tool for finding combinatorial association rules in databases.
  • You can download the source code of the offline version (standalone program) here.
The most important limitations of this online version, compared to the offline one:
  • Databases cannot exceed 3MB.
  • Jobs are automatically terminated after 30min of run time.
