Background

This chapter aims to show:

• that you understand what the problem is
• that you are aware of the current state-of-the-art
• that you can analyse and critique others' work
• that there is an unsolved problem to be investigated

The chapter structure follows roughly these goals

• describe the problem in detail, all issues/aspects
• develop an approach for determining a "good" solution
• describe and analyse previous work   (using this approach)
• conclude that some aspect of the problem is not yet solved
