Detailed Description

Utils for memoization of OccupancySpectrumDistribution objects (optimization)

Function Documentation

memoize()

template<class FilterPolicy = filter_policy::return_always_true, class EditorPolicy = editor_policy::identity>

const ProbabilityDistribution< FilterPolicy, EditorPolicy > & quetzal::coalescence::occupancy_spectrum::memoize::memoize	(	int	k,
		int	N
	)

Store on RAM the entire distributions of occupancy spectrums for every pair \(k\) and \(N\).

Parameters

k	the number of balls (lineages) to throw (coalesce)
N	the nummber of urns (parents)

Returns

A reference on a pre-computed OccupancySpectrumDistribution

Remarks

Builds the distribution the first time that the pair \(\{k,N\}\) is called. Next time the pair is encountered, it returns a reference to the already-computed result.
