Parameters Path Error Density

  • 100 randomized depth-first search trial, where each trial is time-bounded at

one hour. A total of 100 computation hours dedicated in discovering the error.

  • 2 MB of RAM allocated on each machine
  • The Error Discovering Trials is the number of trials that discovered an error

among the initially launched trials (100).
