the solution in O (log) is too simple

N=377

solve

(377/p+p)/2=Q , sqrt[(Q-1)^2/4-(Q-1)+1]=A ,sqrt[(A-1)^2/4-(A-1)+1]=B , (B-1)^2/4=1

explanation

Q=21

(Q-1)^2/4=100


sqrt[(Q-1)^2/4-(Q-1)+1]=9

Q=9

(Q-1)^2/4=16

sqrt[(Q-1)^2/4-(Q-1)+1]=3

Q=3

(Q-1)^2/4=1


I wanted to find in O (1)


so it will be for next time

sorry

I'm not sure what you're saying, but let me know if you address my question

or take up my challenge

Pass those and I'd be happy to help with analysis.

if N=4*G+1

(n-6)-n/2=A

hey
last two questions:
to whom should I compare A, B, C, D, .......?
what is the computational complexity?

I found the first solution on 23 September 2017


https://www.academia.edu/34655158/Tr...ne_in_un_gioco

x=(y+1)*(y+1-2)-(y+1-2)^2


2 =(2+1)*(2+1-2)-(2+1-2)^2
4 =(3+1)*(3+1-2)-(3+1-2)^2
6 =(4+1)*(4+1-2)-(4+1-2)^2
8 =(5+1)*(5+1-2)-(5+1-2)^2
10=(6+1)*(6+1-2)-(6+1-2)^2
12=(7+1)*(7+1-2)-(7+1-2)^2
.....
.....
.....

Your main problem is that you think this is "un gioco"...
Try factoring some 100 digits number with your method. In fact, we would be happy with some 50-70 digits too..

I show you one of the solutions in O(256 * (log_32 () ))


x=(y+1)*(y+1-2)-(y+1-2)^2 A=(y+1)+(y+1-2)+(y+1-2)


2 =(2+1)*(3-2)-(3-2)^2
4 =(3+1)*(4-2)-(4-2)^2
6 =(4+1)*(5-2)-(5-2)^2
8 =(5+1)*(6-2)-(6-2)^2
10=(6+1)*(7-2)-(7-2)^2
12=(7+1)*(8-2)-(8-2)^2
14=(8+1)*(9-2)-(9-2)^2
16=(9+1)*(10-2)-(10-2)^2
18=(10+1)*(11-2)-(11-2)^2
20=(11+1)*(12-2)-(12-2)^2
22=(12+1)*(13-2)-(13-2)^2
24=(13+1)*(14-2)-(14-2)^2
.....
.....

search p=256*G+3 and z mod 32 = 0

p^2+n*p=N , (p-3)/2=(x+1)*(x+1-2)-(x+1-2)^2 , (p-11)/2=(y+1)*(y+1-2)-(y+1-2)^2 ,(x+y)/4=z

example

p^2+n*p=66051^2 , (p-3)/2=(x+1)*(x+1-2)-(x+1-2)^2 , (p-11)/2=(y+1)*(y+1-2)-(y+1-2)^2 ,(x+y)/4=z , p=66051

to move from one p to the other p-2*k you do so N-(2*k)^2-2*k*n

(p-2*k)^2+(n+4*k)*(p-2*k)=N-(2*k)^2-(2*k*n) , (p-2*k-3)/2=(x+1)*(x+1-2)-(x+1-2)^2 , (p-2*k-11)/2=(y+1)*(y+1-2)-(y+1-2)^2 ,(x+y)/4=z

example

(p-2*1)^2+(n+4*1)*(p-2*1)=66053^2-(2*1)^2-(2*1*n) , (p-2*1-3)/2=(x+1)*(x+1-2)-(x+1-2)^2 , (p-2*1-11)/2=(y+1)*(y+1-2)-(y+1-2)^2 ,(x+y)/4=z , p=66053


what do you think?

What number did this factor? How much more work would it take if you doubled the number of digits?

We think you need treatment, at least against some trolling syndrome (we can't imagine that it is something else, any other sane person in the world, over a certain age, like 10 years old or so, would have understood up to now, after so much talk in these threads, and after so many hints from people who know what they are talking about).


This is even not misc math, and we will propose on the mod's board to limit your posting to the blog area in the future.
