## \STATE [algorithmic package]

Posted in Books, Kids, pictures, R, Statistics, Travel, University life with tags , , , , , , , , , on June 8, 2012 by xi'an I fought with my LαTεX compiler this morning as it did not want to deal with my code:

 \begin{algorithmic}
\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}
\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}


(This is connected with my AMSI public lecture on simulation, obviously!)
