I don't know whether it "should" be otherwise, but with Swarm you get the 
same default starting seed every time you run a simulation, unless you 
specify otherwise. If you use the "-s" switch, you will get a new "random" 
starting seed (which depends on the time and the process number) every time 
you run the simulation. Or, with the latest snapshot of Swarm, you can say 
"-S=seedvalue" to specify a specific seed yourself.
