如何避免单列双情形方程的“Overfull \hbox”警告?

如何避免单列双情形方程的“Overfull \hbox”警告?

我有以下涵盖两种情况的方程,并且在我的双列文档中收到“Overfull \hbox”警告:

\documentclass[conference, 10pt]{IEEEtran}
\IEEEoverridecommandlockouts

%% Packages:
\usepackage[utf8]{inputenc} 
\usepackage[T1]{fontenc}
\usepackage{url}                        
\usepackage[cmex10]{amsmath}  
\interdisplaylinepenalty=1000 
\usepackage{mleftright}       
\mleftright                   
\usepackage{amsthm}
\usepackage{booktabs}   

\begin{document}
\begin{equation*}
    \mathbf{1}(x \geq 0) \mathbf{1}(-w \leq y - x \leq 0) =
    \begin{cases}
    \mathbf{1}(0 \leq x \leq w + y), & \text{if $-w \leq y \leq 0$},  \\
    \mathbf{1}(y \leq x \leq w + y), & \text{if $ y \geq 0$}.
    \end{cases}
\end{equation*}
\end{document}

可以进行哪些修改来消除警告而不牺牲方程的清晰度?任何帮助或建议都将不胜感激。谢谢!

我猜不出这是什么意思,但也许你需要分成更多行

在此处输入图片描述

\documentclass[conference, 10pt]{IEEEtran}
\IEEEoverridecommandlockouts

%% Packages:
\usepackage[utf8]{inputenc} 
\usepackage[T1]{fontenc}
\usepackage{url}                        
\usepackage[cmex10]{amsmath}  
\interdisplaylinepenalty=1000 
\usepackage{mleftright}       
\mleftright                   
\usepackage{amsthm}
\usepackage{booktabs}   

\begin{document}

\noindent X\dotfill X

\noindent X\dotfill X
\begin{multline*}
    \mathbf{1}(x \geq 0)
    \mathbf{1}(-w \leq y - x \leq 0)
\\{}  =
    \begin{cases}
    \mathbf{1}(0 \leq x \leq w + y), & \text{if $-w \leq y \leq 0$},  \\
    \mathbf{1}(y \leq x \leq w + y), & \text{if $ y \geq 0$}.
    \end{cases}
\end{multline*}

\end{document}
