Description (last modified by abeham)
A prototype of an expert-system-like optimizer should be implemented that makes algorithm instance suggestions based on FLA information and performance data from an OKB.
This will build on the developments in #2431.

comment:44 Changed 11 months ago by abeham
- 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
