\item \self Consider the following formula in $\mathcal{T}_{EUF}$.

\begin{align}
|
|
\phi_{EUF} \quad := \quad f(x)=f(y) \land f(y)=y \lor f(g(x))=f(f(y)) \land g(x)=x \\ \lor f(x) \neq f(y) \land y \neq g(f(y)) \land x \neq g(x)

\end{align}

Use Ackermann's reduction to compute an equisatisfiable formula in $\mathcal{T}_{E}$.
|
|
|
|
Then perform the graph-based reduction on the outcome of Ackermann's reduction to construct an equisatisfiable propositional formula $\phi_{prop}$.
