Extended Regular Grammars
An extended right regular grammar is one in which all rules obey one of
- B → a - where B is a non-terminal in N and a is a terminal in Σ
- A → wB - where A and B are in N and w is in Σ*
- A → ε - where A is in N and ε is the empty string.
Some authors call this type of grammar a right regular grammar (or right linear grammar) and the type above a strictly right regular grammar (or strictly right linear grammar).
An extended left regular grammar is one in which all rules obey one of
- A → a - where A is a non-terminal in N and a is a terminal in Σ
- A → Bw - where A and B are in N and w is in Σ*
- A → ε - where A is in N and ε is the empty string.
Some authors call this type of grammar a left regular grammar and the type above a strictly left regular grammar.

Famous quotes containing the words extended, regular and/or grammars:
“Whenever there are in any country uncultivated lands and unemployed poor, it is clear that the laws of property have been so far extended as to violate natural right. The earth is given as a common stock for man to labor and live on.... The small landowners are the most precious part of a state.”
—Thomas Jefferson (1743–1826)
“My attitude toward punctuation is that it ought to be as conventional as possible. The game of golf would lose a good deal if croquet mallets and billiard cues were allowed on the putting green. You ought to be able to show that you can do it a good deal better than anyone else with the regular tools before you have a license to bring in your own improvements.”
—Ernest Hemingway (1899–1961)
“A sure proportion of rogue and dunce finds its way into every school and requires a cruel share of time, and the gentle teacher, who wished to be a Providence to youth, is grown a martinet, sore with suspicions; knows as much vice as the judge of a police court, and his love of learning is lost in the routine of grammars and books of elements.”
—Ralph Waldo Emerson (1803–1882)
