Detailed Description

template<class AHitInBoxAlgorithm, class AnotherHitInBoxAlgorithm>
class Belle2::TrackFindingCDC::TwoHitInBoxAlgorithm< AHitInBoxAlgorithm, AnotherHitInBoxAlgorithm >

Predicate class to check for the containment of items in a hough space part with two algorithms.

The resulting weight is added. If one of the two algorithms gives NaN, this particular result is not used (only the other). If both give NaN, the result will also be NaN.
