node without branches matching the next word or word class), the algorithm retraces its<br />

steps back to the last viable branching alternative. This way, the whole tree of possible<br />

constituent analyses is searched in a finite number of steps, and if a given sentence falls<br />

into the subsegment of a language described by the grammar in question, the algorithm<br />

will print out an analysis each time it encounters the ‘end’ symbol (i.e. takes a path<br />

matched by the last word of the sentence).<br />

An example for a simple finite state transition network is shown below:<br />
