Fast Target Assignment by Physical Modelling

On this page, we show some movies of simulations performed similarly to those shown on the previous page. In the original simulations, we used 13,200,000 move trials between two frames. Each move trial simply means that a sensor checks whether to track another target or stay with the actual one. However, the simulations can be speeded up a lot, as the following results show. We decreased the number of move trials by a factor of v, which means that the simulation was roughly done by a factor of v faster. v was chosen in powers of 10. We used v = 10, 100, 1,000, 10,000, and 100,000. We find that we get roughly the same quality of results if we use a value of v up to one thousand. Hereby we show you the resulting movies of our simulations for one of the former cases, namely 100 sensors on a square lattice with a radius R=30, for various numbers of moving targets and all of the velocity factors v mentioned above.

How these results depend on the connectivity between the sensors is shown on the next page.
