Classical Boolean networks (sometimes called CRBN, i.e. Classic Random Boolean Network) are synchronously updated. Motivated by the fact that genes don't usually change their state simultaneously, different alternatives have been introduced. A common classification is the following:

* '''Deterministic asynchronous updated Boolean networks''' ('''DRBN'''s) are not synchronously updated but a deterministic solution still exists. A node ''i'' will be updated when ''t ≡ Q_i (''mod'' P_i)'' where ''t'' is the time step.<ref name=GershensonDrbn>{{cite book|last1=Gershenson|first1=Carlos|last2=Broekaert|first2=Jan|last3=Aerts|first3=Diederik|title=Contextual Random Boolean Networks|journal=Advances in Artificial Life|date=14 September 2003|volume=2801|pages=615–624|doi=10.1007/978-3-540-39432-7_66|arxiv=nlin/0303021|series=Lecture Notes in Computer Science|trans-title=7th European Conference, ECAL 2003|location=Dortmund, Germany|isbn=978-3-540-39432-7}}</ref>

确定性异步更新的布尔网络'（'DRBN'）不会同步更新，但确定性解决方案仍然存在。 当''t ≡ Q_i (''mod'' P_i)''其中''t''是节点时，将更新节点''i'' 时间步长。

当 ''t≡Q_i(''mod''P_i)'' 其中 ''t'' 是时间步长时，''i'' 节点将被更新。'''确定性异步更新布尔网络'''('''DRBN''''s)不是同步更新，但确定性解仍然存在。当 ''t≡Q_i(''mod''P_i)'' 时，''i'' 节点将被更新，其中 ''t'' 是时间步长。

* The most general case is full stochastic updating ('''GARBN''', general asynchronous random boolean networks). Here, one (or more) node(s) are selected at each computational step to be updated.

*最一般的情况是完全随机更新（'''GARBN'''，一般的异步随机布尔网络）。 在此，在每个计算步骤中选择一个（或多个）节点进行更新。
