I'm interested in the simple algorithm for particles filter given here. It seems very simple but I have no idea on how to do it practically. Any idea on how to implement it (just to better understand how it works) ?

Edit:
This is a great simple example  that explain how it works. I've tried to implement it in C++: see my code here, but I'm note sure if I do it the right way. Can you please check if I understood it well, or there are some misunderstanding according to my code ?


Question: "Become acquainted", "be connected" with the connotation of "take the initiative"
Answer: Who exhibited the excellent networking skills, ‘she’ or the ‘more than 20 scholars’? Assuming the first, a clearer way of putting it might be:


  She has excellent networking skills. This was apparent in the way in
  which she became acquainted with more than 20 scholars at the
  conference.


Possible alternatives to became acquainted with are made contact with, exchanged contact details with, or simply met.
