[Retros] 1. Introduction to Retrograde Analysis (Kevin Begley)

[Alain BROBECKER]

I want to repeat my thanks to Nikolai for his
introduction to RA.

I said i recognised a problem as a version of
one by Eric Angelini, but as we all know the
easiest problems can well be found by independant
authors (see for example P0000971), so considering
the "legal" problems are quite simple, Nikolai
has probably used matrix he knows by heart and
hard to credit(?)...

Better, another introduction written by you would
be welcome... Nikolai's work is certainly not
perfect (and none will ever be), but it exists!
I enjoyed it and discovered some ideas i was not
aware of in it (and yes i'm a weak retro fan).

Regards, Alain
