enum fastjet::Strategy

the various options for the algorithmic strategy to adopt in clustering events with kt and cambridge style algorithms.

Enumeration values:

N2MinHeapTiled experimental ...

N2Tiled fastest from about 50..10^4

N2PoorTiled legacy

N2Plain fastest below 50

N3Dumb worse even than the usual N^3 algorithms

Best automatic selection of the best (based on N)

NlnN best of the NlnN variants -- best overall for N>10^4

NlnN3pi legacy N ln N using 3pi coverage of cylinder

NlnN4pi legacy N ln N using 4pi coverage of cylinder

NlnNCam4pi Chan's closest pair method (in a variant with 4pi coverage), for use exclusively with the Cambridge algorithm.

NlnNCam2pi2R
