In our experiments, performance did not vary as much as
we expected. This result suggests that researchers in general are not developing
for specific hardware/software configurations, but recent trends suggest
otherwise, at least with regards to memory. Again, because these systems are
research prototypes, it behooves the developer to be clear about his/her
expectations and anyone subsequently using the system to accommodate those
requests in their studies.
Recommendation 13: As with other factors in planner design, researchers
must clearly state the hardware/software requirements for their planners, if the
design is based on platform assumptions. Additionally, a careful study of memory
versus time trade-offs should be undertaken, given the recent trends in memory
