Adaptive Dynamics

Computing Challenges

  • 10 - 1p Adding solutions to yesterday's puzzles, see Yesterday's Entry
  • The random number generator solution is imperfect, as it limits the total number of seeds to 1e9 since coercing to an integer will create NAs with larger numbers.


 seeds <- 1e9*runif(reps)
 out <- sfSapply(1:reps, function(i){ branch_simulation(seed=seeds[i]) })

Analytic Solutions
