Line 130:

For any particle at any stage of calculations

the LSA maintains the record of only two events:

an old, already processed committed event, which comprises

the processedcommitted event [[time stamp]],

the particle state

(including position and velocity),

Line 140:

and a new event proposed for a future processing

with a similar set of parameters.

The new event is not committed.

Next particle to be examined by the algorithm has

the current minimum of new event times.

At examining the chosen particle,

what was previously the new event, is declared to be the old one

and to be committed,

whereas the next new event is being scheduled,

with its new [[time stamp]], new state, and new partner.

At processingAs the schedulednext new event for a particle is being set,

some of the neighboring particles may update

their non-committed new events to better account for the new

information on what actually has happened in the system

when the previously old event for the particle has been committed.

As the calculations of the LSA progress,
