Evolutionary optimization of layouts for high density free space
... A difficulty for the design of the EA is, that one has to make sure, that the connectors do not overlap. That has to be considered already for the random initialization of the individuals. We do the initialization in the following way: the connectors are initialized one after another and if a new init ...
