我想在投影機區塊中輸入上述演算法,但我堅持插入mathcal symbols
.我嘗試了$\mathcal{Q}$
和\mathcal{Q}
,但兩者都未能返回預期的符號。
我的MWE:
\documentclass{beamer}
\usepackage{listings}
\usetheme{Madrid}
%\lstset{language=Python}
\begin{document}
\begin{frame}[fragile]
\begin{block}{Algorithm}
\begin{lstlisting}
$\mathcal{Q}$
for i in range(10):
foo(arg1, arg2)
bar = qux()
\end{lstlisting}
\end{block}
\end{frame}
\end{document}
更新
\documentclass{beamer}
\usetheme{Madrid}
\usepackage{algpseudocode}
%this code is from: https://tex.stackexchange.com/a/353165/101651
\algnewcommand\algorithmicinput{\textbf{Input:}}
\algnewcommand\algorithmicoutput{\textbf{Output:}}
\algnewcommand\Input{\item[\algorithmicinput]}%
\algnewcommand\Output{\item[\algorithmicoutput]}%
\begin{document}
\begin{frame}[fragile]
\begin{block}{Algorithm}
\begin{algorithmic}
Input: $\mathcal{Q}_{\text{init}}$, \mathcal{A}, and \textit{f}(c).
Initialize: Obtain \writetilde{c_{i}} by solving frac{\delta f(c)}{\delta c_{i}}=0, for i\in\mathcal{N}.Set k = 1, \mathcal{B} = \mathcal{Q}_{init},\mathcal{u}_{i}=\gamma_{ub}(\mathcal{Q}_{init} and \mathcal{l}_{1} = \gamma_\left\{ lb}(\]mathcal{Q}_{init}.
Check the feasibility of problem (17) with given \writetilde{c}.
if feasible then
c_{0} = \writetilde{c};
else
while u_{k} - l_{k} > \epsilon do
Branching:
\begin{itemize}
\item Set \mathcal{Q}_{k} = \mathcal{Q}, where \mathcal{Q} satisfies \gamma_\left\{ lb}(\mathcal{Q} = l_{k}.
\item Split \mathcal{Q} into \mathcal{Q}_{\rm{I}} and \mathcal{Q}_{\rm{II}}, along one of its longest edges.
\item Update \mathcal{B}_{k+1} = (\mathcal{B}_{k}\{\mathcal{Q}_{k}}) \union (\mathcal{Q}_{\rm{I}}, \mathcal{Q}_{\rm{II}}.
\end{itemize}
Bounding:
\begin{itemize}
\item Update \mathcal{u}_{k+1} = \min_{\mathcal{Q}\in\mathcal{B}_{k+1}{\gamma_{ub}(\mathcal{Q})}
\item Update \mathcal{l}_{k+1} = \min_{\mathcal{Q}\in\mathcal{B}_{k+1}{\gamma_{lb}(\mathcal{Q})}
\end{itemize}
Set k=k+1;
end while
Set c_{0} = c_{min};
end if
Output: c_{0}.
\end{algorithmic}
\end{block}
\end{frame}
\end{document}
我輸入的上述演算法有很多錯誤。我首先在 LaTeX 中輸入了這種類型的演算法。因此,如果有人給我預期的程式碼編輯此程式碼以獲得像此演算法一樣的結果,那麼這對我非常有幫助。
答案1
問題是它是一個逐字環境,所以一切是逐字的。為了做到這一點不是逐字你必須使用該選項escapeinside
:
\lstset{escapeinside={@(}{)@}}
這樣之間的任何程式碼@(...)@
都會轉義回 LaTeX。
最佳實踐是使用多個字元進行轉義以避免歧義。也要嘗試選擇不會出現在程式碼中的組合。例如,在Python中,:(...):
由於循環的語法原因,使用將是一個壞主意for
。
\documentclass{beamer}
\usepackage{listings}
\usetheme{Madrid}
%\lstset{language=Python}
\lstset{escapeinside={@(}{)@}}
\begin{document}
\begin{frame}[fragile]
\begin{block}{Algorithm}
\begin{lstlisting}
@($\mathcal{Q}$)@
for i in range(10):
foo(arg1, arg2)
bar = qux()
\end{lstlisting}
\end{block}
\end{frame}
\end{document}
