FHM associates a utility-list [9] to each pattern. Utility-lists FHN: Efficient Mining of High-Utility Itemsets with Negative Unit Profits 21 allow calculating the utility of a pattern quickly by making join operations with utility-lists of smaller patterns. Utility-lists are defined as follows. Definition 8 (Utility-list). Let be any total order on items from I. The utility-list of an itemset X in a database D is a set of tuples such that there is a tuple (tid, iutil, rutil) for each transaction Ttid containing X.

Then, if the sum of iutil and rutil values in the utility-list of P x are no less than minutil, it means that extensions of P x should be explored (cf. Property 7). This is performed by merging P x with all extensions P y of P such that y x and T W U ({x, y}) ≥ minutil, to form extensions of the form P xy containing |P x| + 1 items. The utility-list of P xy is then constructed as in FHM by calling the Construct procedure (cf. Algorithm 3) to join the utility-lists of P , P x and P y. This latter procedure is the same as in FHM [4] and is thus not detailed here.
