Efficient simulation is achieved by employing a highly efficient ordering of the events to be simulated. Specifically, the events to be simulated are grouped into layers (11,21 ,31 ,41) and the layers are simulated in order. Each of the layers consists of events (14-17, 22-24, 32-34, 42-44) that are either strictly independent of the other events in the layer or are dependent of other events in the layer but possess a particular attribute. That attribute is one that permits the use of an associative operator. This operator allows the simulation of N events in O(log N) computation iterations.
