Speeding up evolutionary search by small fitness fluctuations
Speeding up evolutionary search fitness fluctuations
2011/1/5
We consider a fixed size population that undergoes an evolutionary adaptation in the weak mutuation rate limit, which we model as a biased Langevin process in the genotype space. We show analytically ...
On the trajectories and performance of Infotaxis, an information-based greedy search algorithm
