Draw the rest of the Hummingbird

Generation three thousand of a genetic algorithm learning to draw a hummingbird

A genetic algorithm learns to draw a hummingbird:

The video is an animation of three thousand generations of evolution. It starts with a random mix of line segments which are then mutated by adding or removing lines and by changing the start, end and color of existing lines. Each generation has 32 individuals. The best individual is mutated to create the next generation.

For this implementation the best or fittest individual is the one with the least error on a pixel by pixel comparison to a stock art drawing of a hummingbird. Because I care more about the shape than completely filling in the drawing an error outside the figure is penalized three times more than a gap inside the figure.

Color is mutated each generation but not selected for, so it's just changing randomly.

The Sense of an Ending by Julian Barnes

4/5

A personal anti-adventure, gripping and poignant and pedestrian.

 

The Children of the Sky (Zones of Thought, #3) by Vernor Vinge

0/5

Solid, unexpected third installment. Don't read if you haven't read the first two.
