Abstract

In this study, we explore the properties of certain solutions of two Hofstadter-Huber recurrence relations. The first is Hofstadter’s V-recurrence, which is defined by the nested recurrence relation V(n)=V(n−V(n−1))+V(n−V(n−4)). Plus, we introduce another meta-Fibonacci recurrence H(n)=H(n−H(n−2))+H(n−H(n−3)). First, we study a finite chaotic solution to the V-recurrence in order to analyse its generational structure. Then, we explore a new type of infinite solution to nested recurrence relations, finding solutions of this type to both the V-recurrence and the H-recurrence. Our construction relates to systems of nested recurrences that resemble Golomb’s recurrence G(n)=G(n−G(n−1))+1.
