Abstract:

A (rather strange) computer is considered which costs 1 cent to perform each addition but costs nothing to perform a multiplication. It is shown that the addition chain from 1 to n cost maximally ${(\operatorname {Log} n)^{1/2 + o(1)}}$ rather than the classical $\sim \operatorname {Log} n$.
