Description
The iteration is performed only once for each selected
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))))
(do-instances-on-space-instances (instance 'hyp space-instance)
(if (>= (length (space-instances-of instance) 1))
(remove-instance-from-space-instance
instance space-instance)
(delete-instance instance))))
Delete hyp unit instances that
reside on the (bb probable-hyps) space instance that
have a belief value of less than 0.5:
(do-instances-on-space-instances (instance 'hyp '(bb probable-hyps)
:pattern '(< belief .5))
(delete-instance instance))
