To get a better understanding of what the Job Phone Company simulation is supposed to do, let's look at some examples of it in action.
Here is the result of a short run of the program in verbose mode:
jog 10 0.7 17 log Number of events to process: 10 Connection probability: 0.7 Seed for random number generation: 17 Verbose mode...

There were 4 completed calls, in 1.31 hours (simulated time). The average duration of a call was 0.234 hours (simulated time). The average number of active connections was 2.6. Time used: 0 seconds.This program has extra code (not required, but a good idea for debugging) so that it can print out the connections table after each event. Let's look at the output below that it produces when this code is included. Notice that each connection causes two entries to be made in the table, one in which each of the two numbers involved is the key. This is done to allow the connection to be looked up efficiently regardless of which of the two numbers is used as the key.1

Time used: 0 seconds.Here are a few more examples:

There were 435 completed calls, in 4.71 hours (simulated time). The average duration of a call was 0.233 hours (simulated time). The average number of active connections was 134. Time used: 0.55 seconds.With the same parameters except connection probability is 0.9:

There were 4395 completed calls, in 7.14 hours (simulated time). The average duration of a call was 0.23 hours (simulated time). The average number of active connections was 1177. Time used: 3.79 seconds.
How about 100,000 events:
jog 100000 0.7 17 nolog Number of events to process: 100000 Connection probability: 0.7 Seed for random number generation: 17 Silent mode... Completed 100000 events. There were 43374 completed calls, in 10.4 hours (simulated time). The average duration of a call was 0.211 hours (simulated time). The average number of active connections was 1.091e+004. Time used: 77.23 seconds.
There are compiled versions (for SUNs and Windows PCs) of a map version of the program in
/dept/cs/cs230/public/projects/project3called jog, which you can try out with various command-line parameters to give you still more information about what is expected.
