| + | |||
| + | * 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). | ||
