I need to fix the alignment of this LaTeX code.
When I compile it, the output has the wrong alignment of if, for, else statements.
\begin{algorithm}[H]
\caption{:The $ASP\_Tree$ algorithm}
\SetKwInOut{Input}{Input}
\SetKwInOut{Output}{Output}
\Input{TV database and min\_sup }
\Output{Bla bla bla}
\KwData{bla bla bla}
\Procedure{Tree}{$TV_i, min\_sup$}
{
\State {$[Root] \leftarrow [NULL]$} \newline
\For {$i=1$ to $N$} {\label{forins} \newline
{
%\Statex \Comment {\%Comments: insert TV values into the tree based on rules}
\State {$Root \leftarrow TV_1$}
\State {$i \leftarrow i+1$} \newline
\If {TV_i \textgreater Root}
\State Root \gets TV_i
\ELSIF {TV_i\leq Root}
\State i\gets i+1
\ELSE
\State do something interesting
\ENDIF
}
\EndFor
}
\EndProcedure
\end{algorithm}

Answer 1

Your problem lies in the fact that you're mixing notations of different packages, which are inherently incompatible. You should choose either algorithm2e or algorithmicx (which provides algpseudocode and algcompatible), not both.
Here is an algorithm2e implementation of what you might be after:
\documentclass{article}
\usepackage{algorithm2e,amsmath}
\SetKwInOut{Input}{Input}
\SetKwInOut{Output}{Output\,}
\SetKwInOut{Data}{Data}
\SetKwProg{Tree}{Tree}{}{EndTree}
\begin{document}
\begin{algorithm}[H]
\caption{The ASP\_Tree algorithm}
\Input{TV database and min\_sup}
\Output{Bla bla bla}
\Data{bla bla bla}
\Tree{$TV_i, min\_sup$}{
$[\text{Root}] \gets [\text{NULL}]$\;
\For {$i = 1$ to $N$} {
$\text{Root} \gets TV_1$\;
$i \gets i + 1$\;
\uIf {$TV_i > \textup{Root}$}{
$\text{Root} \gets TV_i$\;}
\uElseIf{$TV_i \leq \textup{Root}$}{
$i \gets i+1$\;}
\Else{
do something interesting\;
}
}
}
\end{algorithm}
\end{document}
