Description
The function will be applied only once to each
unit instance, even if the unit instance resides on
multiple space instances.
The pattern t matches all unit instances whose
dimension values overlap the dimensional extent of at
least one space instance in space-instances. The
pattern :all matches every unit instance on a
space instance in space-instances, regardless of
dimensional overlap.
Declared numeric and pseudo
probability pattern operators are also supported, for example:
=&, =$&, =$, =$$, =$$$, and
=% and within&, within$&, within$,
within$$, within$$$, and within%.

Examples
Remove all the hyp unit instances that reside on the (bb
probable-hyps) space instance, deleting those
unit instances that do not reside on any other space instance:
(let ((space-instance
(find-space-instance-by-path '(bb probable-hyps))))
(map-instances-on-space-instances
#'(lambda (instance)
(if (>= (length (space-instances-of instance) 1))
(remove-instance-from-space-instance instance space-instance)
(delete-instance instance)))
'hyp
space-instance))
Delete hyp unit instances that reside on the (bb
probable-hyps) space instance that have a belief value of less than
0.5:
(map-instances-on-space-instances
#'delete-instance
'hyp '(bb probable-hyps) :pattern '(< belief .5))
