Constructor Detail

SimpleRatioAmbiguityAcceptance

public SimpleRatioAmbiguityAcceptance(double ratio)

Simple constructor.

Parameters:

ratio - acceptance ratio for candidate[0]/candidate[1], typically 1.0/2.0 or 1.0/3.0

Method Detail

numberOfCandidates

public int numberOfCandidates()

Get the number of candidate solutions to search for.

Specified by:

numberOfCandidates in interface AmbiguityAcceptance

Returns:

number of candidate solutions to search for

accept

public IntegerLeastSquareSolution accept(IntegerLeastSquareSolution[] candidates)

Check if one of the candidate solutions can be accepted.

If the ratio candidate[0]/candidate[1] is smaller or equal to the ratio given at construction, then candidate[0] will be accepted

Specified by:

accept in interface AmbiguityAcceptance

Parameters:

candidates - candidate solutions of the Integer Least Squares problem, in increasing squared distance order (the array contains at least AmbiguityAcceptance.numberOfCandidates() candidates)

Returns:

the candidate solution to accept (normally the one at index 0), or null if we should still use the float solution
