Bonus Levels

The levels described in this file were created prior to the ICLR19 publication. We've chosen to keep these because they may be useful for curriculum learning or for specific research projects.

Please note that these levels are not as widely tested as the ICLR19 levels. If you run into problems, please open an issue on this repository.

In naming the levels we adhere to the following convention:

  • N2, N3, N4 refers to the number of objects in the room/environment
  • S2, S3, S4 refers to the size of the room/environment
  • in Debug levels the episode is terminated once the agent does something unnecessary or fatally bad, for example
    • picks up an object which it is not supposed to pick up (unnecessary)
    • open the door that it is supposed to open after another one (fatal)
  • in Carrying levels the agent starts carrying the object of interest
  • in Dist levels distractor objects are placed to confuse the agent
