  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.
