how to change the type of vertical line in algorithm environment while minimizing the vertical spacing

Question

I am trying to have a straight vertical line after if and for statements to remove the redundant space in algorithm environment.

I use informs3 class that can be found in this website where you should click INFORMS Journal on Computing Style Files.

Here is a MWE.

\documentclass[ijoc,nonblindrev]{informs3} 
\OneAndAHalfSpacedXII % current default line spacing
\TheoremsNumberedThrough     
\usepackage[linesnumbered,ruled,vlined]{algorithm2e}
\begin{document}
\begin{algorithm}
\DontPrintSemicolon
\For{$i \in V$} {
    \For{} {
        \If{}{
            \uIf{}{
                 $statement$
             }\Else{
                $statement$
             }
        }
    }
}
\Return{x}
\caption{{\sc My Algorithm}}
\end{algorithm}
\end{document}

Also, I'd like to remove the spaces between the lines. None of the recommendations presented in this post Vertical spacing in the algorithm environment works.I would appreciate if someone could help me out.

With the combination of the options lined and noend:

\documentclass[ijoc,nonblindrev]{informs3} 
\OneAndAHalfSpacedXII % current default line spacing
\TheoremsNumberedThrough     
\usepackage[linesnumbered,ruled,lined, noend]{algorithm2e}
\begin{document}
\begin{algorithm}
\DontPrintSemicolon
\For{$i \in V$} {
    \For{} {
        \If{}{
            \uIf{}{
                 $statement$
             }\Else{
                $statement$
             }
        }
    }
}
\Return{x}
\caption{{\sc My Algorithm}}
\end{algorithm}
\end{document}

Or with vlined and \SetVlineSkip{0pt}:

\documentclass[ijoc,nonblindrev]{informs3} 
\OneAndAHalfSpacedXII % current default line spacing
\TheoremsNumberedThrough   
\usepackage[linesnumbered,ruled,vlined]{algorithm2e}
\begin{document}
\begin{algorithm}
\DontPrintSemicolon
\For{$i \in V$} {
    \For{} {
        \If{}{
            \uIf{}{
                 $statement$
             }\Else{
                $statement$
             }
        }
    }
}
\Return{x}
\caption{{\sc My Algorithm}}
\end{algorithm}
\end{document}

The vertical spacing between the rows of the algorithm is quite large, since you used \OneAndAHalfSpacedXII in the preamble. To locally decrease the linespacing in the algorithm, you can use \SingleSpacedXII inside of the algorithm environment as shown in teh following example:

\documentclass[ijoc,nonblindrev]{informs3}
\OneAndAHalfSpacedXII % current default line spacing
\TheoremsNumberedThrough   
\usepackage[linesnumbered,ruled,lined, noend]{algorithm2e}
\begin{document}
\begin{algorithm}
\SingleSpacedXII
\DontPrintSemicolon
\For{$i \in V$} {
    \For{} {
        \If{}{
            \uIf{}{statement}\Else{
                $statement$
             }
        }
    }
}
\Return{x}
\caption{{\sc My Algorithm}}
\end{algorithm}
\end{document}
