Evolving towers in a 3-dimensional simulated environment

We describe a system that uses evolutionary computation to evolve tower-like structures. The construction takes place in a computer simulated gravitational environment. The evolution targets the morphology; each chromosome carries structural description of the entity. Fitness functions evaluate the structural integrity and "goodness" of each individual based on indicators such as joint tension, center of gravity, position in space, height, etc. Twelve evolution-tests were performed and all successfully reached tower solutions.
