Chapter notes

Bollobás [44], Hofri [151], and Spencer [283] contain a wealth of advanced probabilistic techniques. The advantages of randomized algorithms are discussed and surveyed by Karp [174] and Rabin [253]. The textbook by Motwani and Raghavan [228] gives an extensive treatment of randomized algorithms.

Several variants of the hiring problem have been widely studied. These problems are more commonly referred to as "secretary problems." An example of work in this area is the paper by Ajtai, Meggido, and Waarts [12].
