Detailed Description

Container of numerical points equipped with an -tolerance and a random weight vector used to bucket approximately equal points.

Note

AI-generated documentation. Verify against the source before relying on it.

A point hashes to the integer rounding of , so points within mEpsilon of each other land in the same bucket and can be deduplicated. The RealVector mWeights either comes from the caller or is filled by the (epsilon, n) constructor with normalised random numbers. Used by the path-tracker to recognise coincident endpoints.
