A fuzzy aspect is introduced into L systems and some of its properties are
investigated. The relationship between fuzzy L languages and the fuzzy lang
uages generated by fuzzy grammar defined by Lee and Zadeh is elucidated. Th
e concept of fuzzy entropy of a string is proposed as a measure of fuzzines
s of the latter. Some relationship between fuzzy L systems and the ordinary
L systems is discussed. (C) 2001 Elsevier Science B.V. All rights reserved
