\title{Pairing Heap}
\author{Hauke Brinkop and Tobias Nipkow}
\maketitle

\begin{abstract}
  This library defines three different versions of pairing heaps: a
  functional version of the original design based on binary
  trees~\cite{FredmanSST86}, the version by Okasaki~\cite{Okasaki} and
  a modified version of the latter that is free of structural invariants.

The amortized complexities of these implementations are analyzed in the AFP article
\href{http://isa-afp.org/entries/Amortized_Complexity.shtml}{Amortized Complexity}.
