crossings_in_window()

template<typename LatticeT , typename CellT >

size_t MayaFlux::Kinesis::SymbolicTrajectory< LatticeT, CellT >::crossings_in_window ( size_t  window ) const

inline

Crossings within the most recent window observations.

Parameters

window

Number of recent observations to examine, clamped to the trajectory's retained history capacity

Returns

Count of adjacent-pair differences within the window

Distinct from crossing_count(): this only looks at the retained window, so it answers "how much boundary-crossing has happened recently" rather than "how much has happened ever."
