TeX - LaTeX Asked by Open the way on February 14, 2021
I am preparing a presentation with beamer from a previous paper written in latex. I want to insert in a slide the pseudocode
begin{algorithm}
begin{algorithmic}[1]
FOR{$i=1$ to $N$}
FOR{$j=1$ to $JJJJ}
STATE $energy[i*JJJ+j] =$
$ interpolate(AAA[i*JJJ+j], ZZZ)$
ENDFOR
ENDFOR
end{algorithmic}
caption{pseudocode for the calculation of }
label{alg:seq}
end{algorithm}
but I get problems since the beamer document does not compile. I tried to use the same packages that in the latex document. I also tried to find examples through google but nothing. Could you tell me what is wron here or how could I add pseudocode in beamer )examples on the net, etc)?
The floating object algorithm
doesn't behave well with beamer (which onviously disables floating objects). To prevent problems you can 1) use the H
placement specifier for algorithm
, or 2) drop the algorithm
environment and use the captionof
command from the caption
package if a caption is needed. The following example shows the first approach:
documentclass[12pt]{beamer}
usepackage{algorithm,algorithmic}
begin{document}
begin{frame}
begin{algorithm}[H]
begin{algorithmic}[1]
FOR{$i=1$ to $N$}
FOR{$j=1$ to $JJJJ$}
STATE $energy[i*JJJ+j] =$
$ interpolate(AAA[i*JJJ+j], ZZZ)$
ENDFOR
ENDFOR
end{algorithmic}
caption{pseudocode for the calculation of }
label{alg:seq}
end{algorithm}
end{frame}
end{document}

algorithmic
and algorithm2e
or algorithm
)float
package with H
option for the floating algorithm environment option to get a fixed positionfragile
option for the frame if you get strange errors, it can fix problems with verbatim text and listingsCompilable example:
documentclass{beamer}
usetheme{Singapore}
usepackage{algorithm2e}
usepackage{algorithmic}
usepackage{float}
begin{document}
section{Test}
begin{frame}[fragile]
begin{algorithm}[H]
begin{algorithmic}[1]
FOR{$i=1$ to $N$}
FOR{$j=1$ to $JJJJ$}
STATE $energy[i*JJJ+j] =$
$ interpolate(AAA[i*JJJ+j], ZZZ)$
ENDFOR
ENDFOR
end{algorithmic}
caption{pseudocode for the calculation of }
label{alg:seq}
end{algorithm}
end{frame}
end{document}

We add a new slide to Beamer documentation, using this begin{frame}...end{frame}
and algorithm using begin{algorithm}...end{algorithm}
If you try to directly embed algorithm in the frame it would not work.
Therefore use scalebox{}{...}
Syntax:
begin{frame}
scalebox{1}{begin{algorithm}...end{algorithm}}
end{frame}

Yeah. None of this works for me. I have been scouring for answers for two or three days and seen yet other solutions that don't work for me. I'm betting that if you're using latex 2020 by han the tanh then you're here reading this. Go ahead and downvote me all you want, but you can always make it look good enough with tabbing inside of a block environment. You can even enclose each printing line within an uncover for extra dramatic effect.
begin{frame}
frametitle{My Procedure}
begin{block}{}
begin{tabbing}
uncover<2- | alert @2>{My=Fun($x,y$)=}
uncover<3- | alert @3>{>Let $ell=1,$ >~~$epsilon_0=1,w_0=x,$ and $z_0=y$}
uncover<4- | alert @4>{>While >$(epsilon_{ell-1} >$ tol $)$}
uncover<5- | alert @5>{>>Let $w_{ell}$ be the solution to $w = G(w z_{ell-1})$}
uncover<6- | alert @6>{>>Let $z_{ell}$ be the solution to $z = G(w_{ell-1} z) + H(z)$}
uncover<7- | alert @7>{>>Let $epsilon_{ell}= |w_{ell} - w_{ell-1}| + |z_{ell} - z_{ell-1}|$}
uncover<8- | alert @8>{>End While>}
uncover<9- | alert @9>{End MyFun>}
end{tabbing}
end{block}
end{frame}
