In case partial generations were produced, they can be automatically dropped by
setting "IncludePartialGenerations" to False. Compare
for instance
In[] := WolframModel[{{1, 2}} -> {{1, 3}, {1, 3}, {3, 2}},
{{1, 1}}, <|"MaxEvents" -> 42|>]
with
In[] := WolframModel[{{1, 2}} -> {{1, 3}, {1, 3}, {3, 2}},
{{1, 1}}, <|"MaxEvents" -> 42|>,
"IncludePartialGenerations" -> False]
One neat use of this is producing a uniformly random evolution for a complete number of generations:
In[] := WolframModel[{{1, 2, 3}, {2, 4, 5}} ->
{{6, 6, 3}, {2, 6, 2}, {6, 4, 2}, {5, 3, 6}},
{{1, 1, 1}, {1, 1, 1}}, <|"MaxEvents" -> 10000|>, "FinalStatePlot",
"EventOrderingFunction" -> "Random",
"IncludePartialGenerations" -> False]
