I am trying to make a flowchart in Latex, I want to put some of steps in a coloured box with a label, e.g. Deterministic Annealing, I added scope part but it doesn't compile with the new change.
\documentclass[useAMS,usenatbib,usegraphicx]{mn2e}
\usepackage{verbatim}
\usepackage{bm}
\usepackage{subfigure}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric,backgrounds,fit,arrows}
\tikzstyle{decision} = [diamond, draw,
text width=4.5em, text badly centered, node distance=3cm, inner sep=0pt, minimum height=5em]
\tikzstyle{block} = [rectangle, draw,
text width=5em, text centered, rounded corners, minimum height=5em]
\tikzstyle{line} = [draw, -latex']
\tikzstyle{cloud} = [draw, ellipse, node distance=2cm,
minimum height=2em]

What I basically want to have in my flow-chart:
1. The written labels and coloured-boxes should not overlap with each other and with lines or boxes.
2. Figure out how to make the boxes appear which are missing again.
Update:
Could somebody point out what would be my mistake?
\documentclass{...}and the required\usepackage{...}lines, and ends with\end{document}. If your code sample is immediately compilable, it is much easier for us to provide help. – eiterorm Sep 11 '14 at 13:06\usepackages are involved to makeflowchart. – Dalek Sep 11 '14 at 13:12cloud,block,lineanddecisionare undefined. Therefore the custom style definitions should be included. – eiterorm Sep 11 '14 at 13:58
