src (folder)

	java source files:

	Apriori.java

		Class implementing Apriori algorithm which containing a main method

	FPGrowth.java

		Class implementing FP-Growth algorithm which containing a main method

	FPTree.java

		Class of FPTree object

	HeaderNode.java

		Class of header node object used to generate the header table in FP-Growth

	HeaderComparator.java

		Class of comparator used to sort the header table

	AprioriImproved.java

		Class implementing my improved Apriori algorithm which containing a main method

This program implements Apriori, FP-Growth, my improved Apriori algorithms.

Apriori and FP-Growth are generally based on the description and the pseudocode provided in the textbook.

For my improved algorithm, I used the hash table improvement and transaction scan reduction improvement strategies, for more details, please see my report and code.
