Does the metric account for possible floating point error in determining whether a node is within threshold distance in the Z-direction?
A. Based on extensive testing, we believe that the metric should not produce floating point errors. However, this possibility cannot be excluded a priori. Therefore, an updated version of the metric is available for download (in substitution of the previous program) from the same original link on this site, as of the posting date of this FAQ. This new version of the metric provides a small additional margin to the Z component of the distance threshold in order to ensure that no floating point error can affect scoring. Although we invite all contestants to use their judgment, we do not recommend switching to the new metric in light of the lack of any impact on scoring found during testing of the metric. If an incorrect score due to floating point error is suspected, please report the incident with relevant details.
