One can enable the search of multilevel point sets in LatNet Builder by changing the value of the –multilevel option with:

--multilevel true

The combiner used to combine the merit value of each nested level is specified with the option –combiner which can take one of the following values:

–combiner sum to sum the individual merit values of all nested levels;
–combiner max to select the maximum individual merit value across all nested levels;
–combiner level:max to select the individual merit value of the nested level with the largest number of points (the highest level); or
–combiner level:m to select the individual merit value of the \(m\)th nested level.

Ideally, multilevel normalizations should be used with multilevel point sets so that the merit value of each nested level ranges on the same scale. You can look at this page to learn how to tell LatNet Builder to use such normalizations.
