The Editor noted: Go to CTAN, click on `Search` and search for `seminar` where you will get several packages making seminars in pdf format.

=== argmax ===

(A tip from Wikipedia)

LaTeX has no built-in \argmax command. Most people get around this by using \arg\max. This is undesirable, because

    * it causes a small space to appear between the words "arg" and "max" (as seen above),
    * a subscripted variable will appear centered beneath the word "max", instead of centered beneath the whole word.

Both of these effects can be seen in the examples above. The following command can be used to define an \argmax command in LaTeX.

  \newcommand{\argmax}{\operatornamewithlimits{argmax}}

Place it in the header of your LaTeX document. It can then be used as follows:

  \hat{e} = \argmax_{e} \Pr(e | f)

This gives a much nicer appearance.
