#2457: removed algorithm instances that do not appear in any run

16:21 Changeset [13803] by abeham

#2457:

changed expected runtime calculation
- now outputs positive infinity instead of nan when no run was successful
- now filters outliers in successful and unsuccessful runs by using two standard deviations of the mean of successful runs as lower bound
  - this change allows having unsuccessful runs in the database with low evaluations / runtime (e.g. due to being aborted early or from an experiment where the max budget was lower)
worked on recommendation algorithms
- implemented several performance measures (absolute error, absolute log error, ndcp, kendall's tau) to evaluate the ranking

13:47 Changeset [13784] by pfleck: #2591 Made the creation of a GaussianProcessModel faster by avoiding additional iterators during calculation of the hyperparameter gradients.
The gradients of the hyperparameters are now calculated in one sweep and returned as IList, instead of returning an iterator (with yield return).
This avoids a large amount of Move-calls of the iterator, especially for covariance functions with a lot of hyperparameters.
Besides, the signature of the CovarianceGradientFunctionDelegate is changed, to return an IList instead of an IEnumerable to avoid unnececary ToList or ToArray calls.
