Added a memory efficient PRNG (FastRandom) and a specific operator to create new FastRandom PRNGs with r4243.

Made some additional changes in r4258 which should be reviewed by gkronber again.

Open questions/points:

  • Do we have to consider any licensing issues when integrating FastRandom into HeuristicLab (e.g. add a copyright note, license text, etc.)?
  • Are we allowed to add the GPL header to FastRandom.cs? If yes, please do so.

Reviewed r4258, looks good.

comment:7 Changed 14 years ago by gkronber

There is no licence information given for the original code of FastRandom. Therefore it should not be a problem to use the code in HeuristicLab. I would not add a GPL header to the file. Instead just leave the original comments of the author (which includes the original authors name).
