- Thoughts.
- Let’s go through it.
- 4hnw=N(nh+hw+wn)
- hmm
- It’s simply made so that if you do a full search, you won’t get there in time.
- Maybe we should do a full search and sample for small values.
- At any rate, mod n shows that Nhw is a multiple of n and so on.
- Official Explanation
- Searching for three values will not be done in time, but searching for two values will be done in time.
- All search with wide judgment
- Is f(a,b,c) equal to d for integers a,b,c?” is a narrow decision
- Find c from a, b, d and ask, “Is c an integer?” is a broad decision
- Searching for three values will not be done in time, but searching for two values will be done in time.
