This is the third of the series of books dealing with the theoretical and computational aspects of the classical Tower of Hanoi Problem (THP) and its various generalizations. Chapter 12 treats two 3-peg variants of the THP due to Minsker, namely, the Little Tower of Antwerpen and the Tower of Antwerpen Chapter 13 re-considers the Star Puzzle, derives some local-value relationships and then finds the solution directly from the corresponding recurrence relation Chapter 14 deals with the variant where the "divine" rule is relaxed, so that, during the transfer process, (at most) r times, a disc may be placed directly on top of a smaller one Chapter 15 analyzes in detail the recurrence relation introduced by Matsuura to find some interesting properties satisfied by the optimal value function, and then finds an independent solution Chapter 16 considers the optimality of the pms of the p-peg (p 4) THP The final Chapter 17 gives some open problems
