* [[Chain of responsibility pattern]]: Command objects are handled or passed on to other objects by logic-containing processing objects

* [[Command pattern]]: Command objects encapsulate an action and its parameters

* "Externalize the Stack": Turn a recursive function into an iterative one that uses a stack.<ref>http://c2.com/cgi/wiki?ExternalizeTheStack</ref>

* [[Interpreter pattern]]: Implement a specialized computer language to rapidly solve a specific set of problems

* [[Iterator pattern]]: Iterators are used to access the elements of an aggregate object sequentially without exposing its underlying representation

* [[Null Object pattern]]: designed to act as a default value of an object

* [[Observer pattern]]: aka Publish/Subscribe or Event Listener. Objects register to observe an event which may be raised by another object

** Weak reference pattern: De-couple an observer from an observable.<ref>http://c2.com/cgi/wiki?WeakReferencePattern</ref>

* [[Protocol stack]]: Communications are handled by multiple layers, which form an encapsulation heirarchy.<ref>http://c2.com/cgi/wiki?ProtocolStack</ref>

* [[State pattern]]: A clean way for an object to partially change its type at runtime

* [[Strategy pattern]]: Algorithms can be selected on the fly
