This is highly problem dependent... and you appear to already know the answer. Note that some differential evolution solution approaches may benefit from parallelizing evaluation of generations since within that sub-problem the optimization dependencies don't apply. A theoretical discussion fo

[R] Optimization with Parallel Processing Functions/Packages

2018-11-07 Thread Doran, Harold
More of a general query, but looking to see if others have successfully used something like the foreach package (or other parallel style functions) with certain functions that minimize likelihood or objective functions (e.g., optim/nlminb). I have had great success with embarrassingly parallel
