Galapagos + Kangaroo (3-body problem)

The coloured lines on the left are the paths of 3 particles acting in accordance with Newton's laws of motion and attracted to each other by gravity. This simple system behaves chaotically - small changes in starting conditions produce large changes in the end result.

Galapagos is optimising the starting position(blue) of one of the particles so that its end position(green) is as close as possible to a target(white).

This is just a first test of combining these components - obviously the next step is to try it with a structure.
