you're probably right, but I have never advised to develop a new
simplification algorithm :-)

I am a "mathematical" as a hobby, I have only met a "little problem"
with the RDP algorithm and I reported it, and I had fun writing an
algorithm for fun but no idea of proposing developments in this

thank you for your report, we'll take a look soon as I can;
