I think it'd be nice if the final web users could see a percentage of the
progression of the computations of the algorithm.

Most of them consist on repeated operations inside one or more loops and
the program can overwrite a text file with that percentage. It's very
simple, and of course it doesn't have to be mandatory for all the
publications.

The page could poll this value every 10 seconds for example and update a
progress bar.

It is very easy to implement and I think that this is needed to make the
user feel that the algorithm is really being computed and when is it going
to finish.
