public String getName()
LaterationAlgorithm
The name should not be too long, e.g. less than 20 chars.

public Point2d localize(Point2d[] anchors, double[] ranges, Point2d actualPosition, ErrorModel errorModel, int width, int height)
LaterationAlgorithm
The size of the anchor and measured ranges array must be at least 3.
The actual position of the mobile node is passed to this method to allow the development of some sort of "cheating algorithm" which does some sort of optimum selection along a set of different algorithms.
The error model can be used by algorithms to determine the current average and maximum distance measurement error.

- The parent frame of the new dialog.public static Point2d multilaterate(Point2d[] anchors, double[] ranges, double[] mfAttrs)
This might be useful if one is only interested in the result and not
the additional features of the BasicLaterationAlgorithm
class.

- The measured distances to the anchor/reference nodes.mfAttrs
- The attributes that characterise the fuzzy membership
