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

[QUOTE=JohnFullspeed;266012]In fact when we say 'Eratosthenes sieve' which is the math concept:

1- The method of removing all bad values to have the good
[Any program that does this for a large class of "bad" values in an attempt to find a small class of "good" values is referred to as a "sieve", as in NFS, MPQS, Sieve of Aitkin, Sieve of Eratosthenes.]
2 The method it self: taker p and invalidate p1,p2 p3,p4
[This is the sieve of Eratosthenes...eliminating multiples of P from your list of possible prime numbers].

The two : how to make the prime list?.

The sieve of John Fullspeed must either
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
