algorithmicx: shorten algorithm

Question

My algorithms takes up too much space in the document. I would like to do 2 things:

set the width bigger, so the lines which does not fit to a single line would do
remove lines with end keywords (i.e. closing tags or whatever they are called)

Are these things possible?

Sorry if these question are lame, but I'm pretty new to TeX, I use LaTeX only for algorithms, I'm writing my document in another format.

UPDATE: Example:

Complete document:

\documentclass{article}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{amsmath}
\begin{document}

\begin{algorithm}

\begin{algorithmic}[1]

\Function {NMS3D}{$T : array[1..w, 1..h, 1..d], n: int$}
    \State \Comment $(2 n +1) \times (2 n +1) \times (2 n +1)$ szomsz\'eds\'gban keress\"uk a lok\'alis maximumokat 
    \State label \textbf{mainloop:}
    \ForAll {$(i, j, k) \in \{ n, 2n+1, ... \}^3 \cap [1..w - n] \times [1..h - n] \times [1..d - n] $}
        \State \textbf{initialize:} $(i_{max}, j_{max}, k_{max}) \gets (i, j, k)$
        \ForAll {$(i_2, j_2, k_2) \in [i, i+n] \times [j, j+n] times [k, k+n]$}
            \If {$T[i_2, j_2, k_2] > T[i_{max}, j_{max}, k_{max}]$}
                \State $(i_{max}, j_{max}, k_{max}) \gets (i_2, j_2, k_2)$
            \EndIf
        \EndFor
        \ForAll {$(i_2, j_2, k_2) \in [i_{max}-n, i_{max}+n] \times [j_{max}-n, j_{max}+n] \times [k_{max}-n, k_{max}+n] 
            - [i, i+n] \times [j, j+n] \times [k, k+n]$}
            \If {$T[i_2, j_2, k_2] > T[i_{max}, j_{max}, k_{max}]$}
                \State \textbf{continue} mainloop
                \State \Comment a maximum jel\"olt t\'ul k\"ozel van egy m\'asik maximumhoz, elvetj\"uk
            \EndIf
        \EndFor         
        \State $list_{max} \stackrel{add}{\longleftarrow} (i_{max}, j_{max}, k_{max})$
    \EndFor
    \State \textbf{return} $list_{max}$
\EndFunction


\end{algorithmic}
\end{algorithm}
\end{document}

Here is the result, corrected with red, on what I would like to be changed (with MS Paint, yeah I do have some epic Paint skillz right?):

Comments are in Hungarian, don't mind that

Can you post an example document so we can see what you're working with? — Jack Henahan, Jun 17 '11 at 19:17

Essentially, it's a matter of page geometry. \usepackage{fullpage} works, for instance, but you can probably also fool around with the geometry package to get a more customizable effect.

Also, see One inch margins and the geometry package.

As for the second point about removing the ends, section 4 of algorithmicx's documentation describes customizing blocks.

Edit: Here's an example.

If you add \algnotext{EndFor}, For blocks will print no end. You can then apply this to EndIf and anything else you need.

\documentclass{article}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{amsmath,fullpage}
\algnotext{EndFor}
\algnotext{EndIf}
\begin{document}

\begin{algorithm}

\begin{algorithmic}[1]

\Function {NMS3D}{$T : array[1..w, 1..h, 1..d], n: int$}
    \State \Comment $(2 n +1) \times (2 n +1) \times (2 n +1)$ szomsz\'eds\'gban keress\"uk a lok\'alis maximumokat 
    \State label \textbf{mainloop:}
    \ForAll {$(i, j, k) \in \{ n, 2n+1, ... \}^3 \cap [1..w - n] \times [1..h - n] \times [1..d - n] $}
        \State \textbf{initialize:} $(i_{max}, j_{max}, k_{max}) \gets (i, j, k)$
        \ForAll {$(i_2, j_2, k_2) \in [i, i+n] \times [j, j+n] times [k, k+n]$}
            \If {$T[i_2, j_2, k_2] > T[i_{max}, j_{max}, k_{max}]$}
                \State $(i_{max}, j_{max}, k_{max}) \gets (i_2, j_2, k_2)$
            \EndIf
        \EndFor
        \ForAll {$(i_2, j_2, k_2) \in [i_{max}-n, i_{max}+n] \times [j_{max}-n, j_{max}+n] \times [k_{max}-n, k_{max}+n] 
        - [i, i+n] \times [j, j+n] \times [k, k+n]$}
            \If {$T[i_2, j_2, k_2] > T[i_{max}, j_{max}, k_{max}]$}
                \State \textbf{continue} mainloop
                \State \Comment a maximum jel\"olt t\'ul k\"ozel van egy m\'asik maximumhoz, elvetj\"uk
            \EndIf
        \EndFor         
        \State $list_{max} \stackrel{add}{\longleftarrow} (i_{max}, j_{max}, k_{max})$
    \EndFor
    \State \textbf{return} $list_{max}$
\EndFunction
