- Here's our source code.
Errata
- 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.
Misc
- A simplified version of the problem was proven to be NP-hard in 2020.
- We got simulated annealing to work in a paper published at ICCC'20.
