% Structuring a talk is a difficult task and the following structure
|
|
% may not be suitable. Here are some rules that apply for this
|
|
% solution:
|
|
|
|
% - Exactly two or three sections (other than the summary).
|
|
% - At *most* three subsections per section.
|
|
% - Talk about 30s to 2min per frame. So there should be between about
|
|
% 15 and 30 frames, all told.
|
|
|
|
% - A conference audience is likely to know very little of what you
|
|
% are going to talk about. So *simplify*!
|
|
% - In a 20min talk, getting the main ideas across is hard
|
|
% enough. Leave out details, even if it means being less precise than
|
|
% you think necessary.
|
|
% - If you omit details that are vital to the proof/implementation,
|
|
% just say so once. Everybody will be happy with that.
