Experiments were run on problems drawn from two domains. The first
was the artificial domain, , originally described in
 and shown in Figure 8.
Testing was done on problems which were randomly generated from this domain
with the restriction that they always
contain the goal .
The Logistics Transportation domain of
 was adopted for the second set of experiments.
Eight packages and one airplane were randomly distributed over
Problem goals represented the task of getting one or more packages
to a single destination airport.
The FLY operator was augmented with a delete condition which
prevented planes from visiting the same airport more than once.
This meant that
replay failed if there was an
extra package to be transported which was off the previous route taken
by the plane.
