Non-Derivable Itemsets

Your goal here is to write a program to compute whether an itemset is derivable or not. The program should take as input the following two files:

  • FILE1: A list of itemsets with their support values (one per line). See the file: itemsets.txt (the format is "itemset - support"; one per line)

  • FILE2: A list of itemsets (one per line), whose support bounds have to be derived. See the file: ndi.txt

Your program should output for each itemset in FILE2 the following info:

itemset: [l,u] derivable/non-derivable

where l and u are the lower and upper-bounds on the support.
