this is the best logarithmic implementation I could think of.
I leave the implementation to you expert programmers


pure logarithm

N=507


3*(((2*190-3*y+1)/24)+3*x*(x+1)/2)+1=A

then
not to test at any level of log y
log y must be overcome

example

3*(((2*250-3*(1-y)+1)/24)+3*x*(x+1)/2)+1=A
,
sqrt((1-y)^2)=sqrt((2*a-1)^2)

if I am not wrong this is the demonstration

((2*(3*N-1)/8-3*y+1)/24)=x*(x+1)/2-(y+1)/2*(y-1)/2/2
,
p*q=N
,
q=2*(3*x+1-(x-y+1))+1
,
p=2*(3*x+1-(x-y+1))+1-(4*y-2)

hey @CRGreathouse here is your log y

if N=p*q & p+q-4 mod 8 = 0 & (q-p+2)/4=y is odd [but ...]


M=(3*N-1)/8

special formula

Z=(2*M-3*y+1)/24

WTF factorization. Do you think it is a good method?

case:

N=p*q
&
q-p=n
&
n mod 8 = 0
&
p+n/2=3*(2*x+1)

So maybe I found when it's true:

in two cases

"New" same approach that isn't factorization

a * b = N

if N mod 4 = 1

then 2 * N + 2 * a ^ 2 + ((b-a) / 2) ^ 2 = ((3 * a + b) / 2) ^ 2

now i found that in some cases (i don't know which ones)

this is also true
