Center hyperedge (induced by source paper "pairing heaps the forward variant"):
  Abstract: The pairing heap is a classical heap data structure introduced in 1986 by Fredman, Sedgewick, Sleator, and Tarjan. It is remarkable both for its simplicity and for its excellent performance in practice. The "magic" of pairing heaps lies in the restructuring that happens after the deletion of the smallest element. The resulting collection of trees is consolidated in two rounds: a left-to-right pairing round, followed by a right-to-left accumulation round. Fredman et al. showed, via an elegant correspondence to splay trees, that all operations take logarithmic amortized time. They also proposed an arguably more natural variant, where both pairing and accumulation are performed in a combined left-to-right round (we call this the forward variant). The analogy to splaying breaks down for this variant, and its analysis was left open. Since then, no progress was made on this question. #R##N#In this paper we show that the amortized costs of inserting an element and of deleting the minimum in the forward variant of pairing heaps are both $O(\log{n} \cdot 4^{\sqrt{\log{n}}} )$. Our analysis relies on a new potential function that captures parent-child rank-differences in the heap, and may have further applications.
