Evolved Tables

We used our system to generate tables. The fitness function rewarded structures for maximizing: height; surface area; stability/volume; and minimizing the number of cubes.

From Simulation to Reality

Shown below are evolved tables that have been transferred to reality. The plastic models were created with our 3D rapid-prototyping printer.

Table 1 676 cubes 195 character build sequence (which expands to 14552 characters).	Table 1 - built
Table 2 - view 1 663 cubes 524 character build sequence (which expands to 8205 characters).	Table 2 - built
Table 2 - view 2
Table 3 504 cubes 488 character build sequence (which expands to 1296 characters).
Table 3 - Fresh from the printer.	Table 3 - Supports removed.
