How to set algorithm width to avoid overfull \hbox problem

Question

I wrote the following latex text, but the log shows an error that overfull \hbox(10.0pt too wide) detected. I am sure that the algorithmic part exceed the width limit. Even if I type a few words, the overfull error still exists. What should I do to control the algorithmic part width. It indeed exceed width limitation although it looks good. I found a command \SetCustomAlgoRuledWidth{length} in algorithm2e documentation, which package should I import to enable this command?

    \STATE \textbf{Output:} $\vec{w}_i$, $\vec{v}_i$.
