New page

== Strategy Pattern ==
Where algorithms are chosen at runtime

[[Image:strategy.png]]

== Visitor Pattern ==

Separate algorithm from structure

Allows adding new methods to existing structure

Limitation:
* concrete visitor tied to what concrete elements exist
* adding a new concrete element => modifying all visitor algorithms & creating new concrete visitor
