Default tuning spaces vs. Bischl et al. 2021 article

[marineReg]

Hello,
I have a question. I've noticed that several default tuning spaces don't seem to correspond to those in the article by Bischl et al. 2021. Here are a few examples:

• GLMNET
  s: [log(10^-4); log(10000)] instead of [2^-12; 2^12]

• RPART
  minsplit: [log(2); log(128)] instead of [2^1; 2^7]
  minbucket: [log(1); log(64)] instead of [2^0; 2^6]
  cp: [log(10^-4); log(0.1)] instead of [10^-4; 10^-1]

• KNN
  k: [log(1); log(50)] instead of [1; 50]

• SVM
  cost and gamma: [log(10^-4); log(10000)] instead of [2^-12; 2^12]

• XGBOOST
  eta: [log(10^-4); log(1)] instead of [10^-4; 10^0]
  lambda and alpha: [log(10^-3); log(1000)] instead of [2^-10; 2^10]

Is there a reason for this? Sorry if I misunderstood something. Thank you for your assistance.
