num_trials


The number of secondary sample points generated to adjust the location of the primary sample points

Specification

Alias: none

Argument(s): INTEGER

Default: 10000

Description

In general, the variable with the most influence on the quality of the final sample set is num_trials, which determines how well the Voronoi subregions are sampled.

Generally, num_trials should be "large", certainly much bigger than the number of sample points being requested; a reasonable value might be 10,000, but values of 100,000 or 1 million are not unusual.
