How deeply does Advanced Algorithms and Data Structures cover determinism?

Defines repeatability through processing order or starting point, while allowing unspecified ties in OPTICS reachability distances.

Determinism

As explained in Advanced Algorithms and Data Structures

A deterministic algorithm produces the same processing sequence and results for the same input and starting conditions, apart from unspecified tie handling.

Determinism means that fixed input and starting conditions reproduce the same processing sequence and result, except where tie handling is unspecified. DBSCAN is treated as deterministic because traversal order has little influence; OPTICS produces identical results when runs start from the same point, apart from possible reachability-distance ties. section 12.3 section 12.4.3

Repeatability matters differently across algorithms:

For DBSCAN, matching the point order guarantees the same result; its point traversal has less influence than k-means’ random initialization. section 12.3
For difficult optimization problems such as crossing-number analysis, heuristics may relax deterministic guarantees to find a sub-optimal answer in reasonable time. section 16.1
