yes but even if it the two pass by if that interval of passing is in the 1b range we will still gets the x value , because it will be the inverse of it.
iam not looking to shrink anything or subranging it , iam looking rather than the collision the kangaroos looking for iam looking for a space i already have the scalar of
Got it. You lookup by X so you catch either Y or -Y, so points of 2 billion scalars.
But it still sounds like a chance of 1 billion in 2**133, since there's nothing that increases your chances from one try to the next. If you pick a random scalar you'll have a greater and greater problem with already tried scalars, more and more often after around 2**66 tries.
You're better off with an actual BSGS, which sounds like what you're trying to emulate a little. Some variants already handle the Y/-Y optimization to lower the complexity. But you're still looking at 2**133/1 billion total steps, however this is an guaranteed maximum upper bound, unlike your random strategy.
Well I don't have the computing power to make 2**66 tries.
