چکیده
|
Inverse problem of topological indices deals with establishing whether or not a given number is a topological index of some graph. in this paper, we study the inverse topological index problem of some bond additive indices. in [1], it was conjectured that every positive integer except finitely many can be the mostar index and edge mostar index of some $c-$cyclic graph. we solve this conjecture for tricyclic graphs. we also study the inverse albertson index problem and inverse sigma index problem for cacti and for cyclic graphs.
