Math equation in latex (varnothing)
5
In a pseudocode, I would like to assign varnothing to a variable.
My code goes like this:
documentclass[runningheads]{llncs}
usepackage{graphicx}
usepackage{algpseudocode}
usepackage{algorithm}
usepackage{amsmath}
begin{document}
begin{algorithm}
caption{Find...}
begin{algorithmic}[1] State $RS$ $leftarrow$ $varnothing$ end{algorithmic}
end{algorithm}
end{document}
Unfortunately this doesn't work. The error message I got is the following:
State $RS$ $leftarrow varnothing $ The control sequence at the end
of the top line of your error message was never def'ed. If you have
misspelled it (e.g., `hobx'), type `I' and the correct spelling
(e.g., `Ihbox'). Otherwise just continue, and I'll forget about
whatever was undefined. ! Undefined control sequence.
varnothing l.103 ...quad quad $R$ $leftarrow$ $varnothing $
Comment{$R$ is the set ... The control sequence at the end of the top
line of your error message was never def'ed. If you have misspelled
it (e.g., `hobx'), type `I' and the correct spelling (e.g.,
`Ihbox'). Otherwise just continue, and I'll forget about whatever was
undefined.
Do you have any ides on how this can be resolved?
FYI, I've already installed amsmath from texlive-latex-base in debian 9.
Thanks,
Pavlos

varnothing belongs to the set of symbols in the package amssymb. So include it in your preamble as usepackage{amssymb} and you are good to go.
documentclass{article}
usepackage{graphicx}
usepackage{algpseudocode}
usepackage{algorithm}
usepackage{amsmath}
usepackage{amssymb}
begin{document}
begin{algorithm}
caption{Find...}
begin{algorithmic}[1] State $RS$ $leftarrow$ $varnothing$ end{algorithmic}
end{algorithm}
end{document}
