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%
