A note on the full-neighborhood search of Kaandorp and Koole (2007).

We give an efficient method for enumerating Kaandorp and Koole's (2007; Health Care Mgmt Sci 10:217-229) "full neighborhood" of candidate improvement schedules employed by their algorithm's local search for the optimal outpatient appointment schedule. A proposition is given that the first appointment interval is always used in the optimal schedule; this allows convenient indexing within our method.
