[BonnMotion] Creating scenarios with specific starating positions

[cheiden]

Hey Stephan,

If I understood you correctly, I think there are currently no options to 
specify certain starting positions. They usually depend on the seed of 
the random number generator. The only possibility that comes to my mind 
is adding it in the actual code and compiling BM again. You can find it 
in src/edu/bonn/cs/iv/bonnmotion/models/Boundless.java.

You could e.g. add new command line arguments to the parseArg() method 
that specifies new starting locations for the nodes. Then you could 
"restart" your simulation by assigning these positions initially in the 
generate() method.

Hope this helps.

Best regards,
Christian Heiden
