An Exponential Envy-Free Cake Cutting Protocol for $n$ Agents

Abstract

We consider a classical envy-free cake cutting problem. The first limited protocol was proposed by Aziz and McKenzie in 2016 arXiv:1604.03655. The disadvantage of this protocol is its high complexity. The authors proved that the maximum number of queries required by the protocol is $n^{n^{n^{n^{n^n}}}}$. We made minor changes to the Aziz-Mackenzie protocol, improved estimation of the required number of queries and made an algorithm that uses at most $n^{8n^2(1 + o(1))}$ queries.
