Oct 18 Meeting

1. Oct 18 Meeting John Nicholson

2. Outline • Introduction/Status/Overview • Uniform Asexual Selection • What was going on with SOP

3. Introduction/Status/Overview • What do I have in common with a politician? • We have been looking at “uniform” asexual selection recently. The old stuff from April was not uniform, but the new stuff from the last two/three months is uniform.

4. Outline • Introduction/Status/Overview • Uniform Asexual Selection • What was going on with SOP

5. Uniform Asexual Selection • I added this block of code some time over the summer: for (int i=0; i<m_PopulationSize; i++) { for (int j=0; j<numberOfChildrenToCreatePerIndividual; j++) { newIndividuals.add(deterministicallyChooseIndividual(i).reproduceAsexually()); numberOfChildrenCreatedSoFar++; } } • This block is part of the asexual reproduction routine, and uniformly spreads selection among the population as much as possible. • The variablenumberOfChildrenToCreatePerIndividual is the integer part of the asexual reproduction rate. • This block of code has now been parameterized.

6. Outline • Introduction/Status/Overview • Uniform Asexual Selection • What was going on with SOP

7. What was going on with SOP • The short version is that uniform asexual reproduction was going on, where every individual had a child. • I still have some pretty plots, so here they are:

8. 5D-Rastrigin – Population Avg Fitness – 10 Runs

9. 5D-Rastrigin – Best Individual – 10 Runs

10. 7D-Rastrigin – Population Avg Fitness – 10 Runs

11. 7D-Rastrigin – Best Individual – 10 Runs

12. Future Work • Start writing conference paper(s). • Uniform reproduction…this time run simulations without uniform reproduction, and see how results change. • More problems • Ancestral views • GeneSigma analysis
