.SH "DESCRIPTION"
.PP
Performs a best match against the current contacts and returns the slot assignment list\&. New contacts are assigned to unused slots\&.
.PP
The assignments are balanced so that all coordinate displacements are below the euclidian distance dmax\&. If no such assignment can be found, some contacts are assigned to unused slots\&.
.PP
Returns zero on success, or negative error in case of failure\&.
