A dynamic factory is a software concept that in instrumental in implementing the Plugin technology in Mantid.
A factory in software terms is an class that is responsible for creating other objects on demand. In mantid terms the AlgorithmFactory is responsible for creating instances of Algorithms when you need them.
As the factory is dynamic it does not have a set list of objects that it can create instead it knows how to create instances of a particular base class. During execution of the code any object of the appropriate base class can be registered with the factory, and then the factory can be used to create fresh instances of that object.
