Abstract

Two new variants of the Towers of Hanoi problem are proposed. In both variations, one is allowed to put a bigger disk directly on the top of a smaller one under some restrictions. We give procedures to solve these two versions, and prove the optimality of our procedures. Our solution also resolves a problem, which is similar to one of our versions, proposed by D. Wood in 1981.
