Compilation

To compile, simply run javac FPGrowth.java in the root directory of this project.

Execution

To execute, run java FPGrowth <db file> <minimum support threshold>. For example, to run the program on data.txt with a 50% minimum support threshold, one would run

java FPGrowth data.txt 50.

The program has been tested under Java 14 (OpenJDK) on Arch Linux. It has been confirmed to produce equivlalent output to the Apriori algorithm I implemented in Assignment 1 for the following inputs:

  • data.txt at 50%
  • connect.txt at 98%
  • connect.txt at 99%
  • retail.txt at 12%
