For this purpose, fuzzy F-index (briefly FF-index) has been formulated theoretically for the fuzzy zero divisor graphs of the commutative ring Z(n), where n = & wp;(alpha), & wp;1 & wp;2, & wp;(2)(1)& wp;2, & wp;(2)(1)& wp;(2)2, & wp;1 & wp;2 & wp;3 (& wp;1, & wp;2, & wp;3 are primes and alpha >= 3). In particular, a SageMath-based drawing algorithm that embodies the fuzzy graph structures of the rings is presented for application based convenience. Furthermore, a MATLAB based code was created that directly calculate the fuzzy F-index of the fuzzy zero divisor graphs for every non-prime value of n > 1.eninfo:eu-repo/semantics/openAccessAdjacency matrixfuzzy F-indexfuzzy zero divisor graphArticle39144873488610.2298/FIL2514873E2-s2.0-105019535791Q2WOS:001588981400001Q20000-0002-9852-66620000-0002-2632-2193
