"Will Craig, Center for Urban and Regional Affairs, University of
Minnesota, Minneapolis, suggested that Paul Densham, National Center
for Geographic Information and Analysis (NCGIA), State University of
New York, Buffalo, should receive the best paper award for his work
on the integration of GIS, parallel processing and location-allocation
algorithms. However, I would have given the award to Densham's paper on
locaton-allocation and genetic algorithms, co-authored with and superbly
presented by NCGIA's Catherine Dibble.
One concern is how to evaluate the best solution from succeeding
generations. This is trivial with a single criterion but troublesome
with multiple criteria -- especially when the payoff cannot be reduced
to a common denominator. The difficulty of adding apples and oranges
was addressed in another context in the October 1992 "Edge Nodes" column."
