Hi, I have found an error in the testing code that may cause the code to crash on different seeds/starting parameters. In test_get_rank_time(), on line 103, the variable "size" is defined to be a random integer between 0 and SIZE inclusive. Later, on line 106, the function random.randint(1, len(runs)), where len(runs) = size (which can be zero). If size = 0, then on line 106, the function random.randint(1,0) is called, which will throw an error, regardless of what is in our code. Can we either (a) be assured that initial conditions will be chosen such that this error will not occur, and if it does occur, we will not be penalised, or (b) get the error fixed (for instance, by changing line 103 to size = random.randint(1, SIZE) )? Thanks very much!
