我正在尝试通过DEoptim以下方式在 R 中使用

fit <- DEoptim(fn = .obj, lower=lower, upper = upper, 
                control = list(itermax = 100, trace = 1, parallelType = 1, 
                               steptol = 25, reltol = 1e-9, strategy = 6))

但是，DEoptim在并行设置中使用不会在多次运行中重现结果。使用 .串行运行代码时，我没有这个问题parallelType = 0。我尝试在集群中设置种子clusterSetRNGStream以及在代码中使用set.seed，但这也无济于事。

有没有人在尝试DEoptim并行运行时遇到过类似的问题。下面是sessionInfo
