\begin{algorithmic}[1] \STATE N=1000 \STATE $\hat\pi=0$ \FOR {I=1,N} \STATE X=RDN(1), Y=RDN(1) \IF {$\text{X}^2+\text{Y}^2<1$} $\hat\pi$ = $\hat\pi +1$ \ENDIF \ENDFOR \RETURN 4*$\hat\pi/$N \end{algorithmic}

looking on forums for incompatibilities between beamer and algorithmic, and adding all kinds of packages, to no avail. Until I realised one \STATE was missing:

\begin{algorithmic}[1] \STATE N=1000 \STATE $\hat\pi=0$ \FOR {I=1,N} \STATE X=RDN(1), Y=RDN(1) \IF {$\text{X}^2+\text{Y}^2<1$} \STATE $\hat\pi$ = $\hat\pi +1$ \ENDIF \ENDFOR \RETURN 4*$\hat\pi/$N \end{algorithmic}

(**T**his is connected with my AMSI public lecture on simulation, obviously!)
