Effective population size of current human population
Genetics Research, 2011 SummaryIn order to estimate the effective population size (Ne) of the current human population, two new approaches, which were derived from previous methods, were used in this study. One is based on the deviation from linkage equilibrium (LE) between completely unlinked loci in different chromosomes and another is based on the deviation from the Hardy ...

On Counting the Population Size [PDF]
Proceedings of the 2019 ACM Symposium on Principles of Distributed Computing, 2019 We consider the problem of counting the population size in the population model. In this model, we are given a distributed system of $n$ identical agents which interact in pairs with the goal to solve a common task. In each time step, the two interacting agents are selected uniformly at random.
