I have two Cocoa apps that simulate the DSR wireless routing protocol - one is baseline DSR and the other is a variation that I'm attempting to write. Here's the catch: when I run the simulators in one directory, I get one set of results. When I run it from another directory, I get different results. Any idea why? I pass the seed in to the random number generator on the command-line. Example:
Running it again, this time from the parent directory containing the Release directory:
Does anyone have any idea of what is going on? The seeds are the same, and the node placement is randomly generated so considering node 0 is at the same location for both runs, I'd say that part is working correctly. Outside of that, does anyone have any ideas? Also, running it from the same directory gives the same answer. I am very confused
