final bridge design consists of 48 joints and 144 beams, some of the
particles and members having merged or been eliminated during the
topology-cleaning step. Similar procedures were used to generate
the initial guesses for all of our results.
Using this same initial structure, but with constraints that no material may be placed above the deck, we generated a second bridge,
shown in Figure 7. Note that the trusswork under the deck has converged to a single, thick spine. This spine is more conservative of
materials than the rectilinear trusswork in Figure 4, but in the earlier
case the constraints to keep the joints in vertical planes prevented it
from arriving at this solution.
