Math concpt
In fact when we say 'Eratosthenes sieve' which is the math concept:
1 The method of removing all bad values to have the good 2 The method it self: taker p and invalidate p1,p2 p3,p4 The two : how to make the prime list?. i/e what a new sieve must do to be a new sieve Thanks John Last fiddled with by JohnFullspeed on 20110710 at 16:27

1) Do something useful that is different than finding prime numbers (and do it in a way not obviously equivalent to someone else's way of doing it) or 2) Find prime numbers in a way that is not obviously equivalent to one of the known sieves. If you want to do either, you will need to carry out Richard Silverman's advice, and not just the part directed to you. That famous professor you mentioned in another thread might also be able to give you some pointers, or help you get a degree in mathematics. The third, more likely possibility is that you implement eratosthenes sieve better than others. It's still a rough task; begin by studying jasonp's code and others.

1 Do something new: I begin by creating a List with all the primed not 2 < x < n 2 I remove composite value of my list not the multiple n 3 My sieve go speeder that all the actual sieve for a technical reason not because a better implementation..? My sieve is especial good for twin research and Sophie Germain it gives strong candidates ((not all the primes) It create a twin mask that you can use starting from arbitrary number You need less tha1 second to find candidats and less 1 second to says if is a twin of a SG. Is It a new sieve ora sppeder version of etastho... The suestion is tha: well qualify the method John PS I don't understad Quote:
