This page is dedicated to the EVOSTAR'19 publication "Paintings, Polygons and Plant Propagation".
These are the target bitmaps used in our experimental runs.

Painting provenance (recovered 31-9-2018):
BACH: Wikipedia, Public Domain (https://en.wikipedia.org/wiki/Johann_Sebastian_Bach)
DALI: Wikiart, Fair Use (https://www.wikiart.org/en/salvador-dali/the-persistence-of-memory-1931)

These are the constellations from our last figure:

A movie clip of the algorithm at work.

- Here's our source code.
- In equation (7), the factor (1−fi) should be just (fi). The typo is just in the paper, not in the source code, and therefore doesn't affect the results (see organisms.py, line 138).
- In equation (9), the factor 9v/4 is incorrect; the experiments were done with 13v/5. The factor 1/nmax from the same formula was never in the experiment (see organisms.py, line 143). It is most likely a uncorrected textual remnant from an earlier probe. In general, we have been looking for a good way to transfer the PPA-algorithm to this problem, and many adaptations are possible.
A simplified version of the problem was proven to be NP-hard in 2020.
