| چکیده | ||
| The total irregularity is a type of graph invariant and for a given simple graph $ G$ is calculated by the formula, $irr_t(G)=\dfrac{1}{2}\sum_{\{u,v\} \subseteq V(G)}\mid deg_Gu-deg_Gv\mid$, in which $deg_Gv$ is the degree of the vertex $v$ of $G$. This paper aims to offer a classification of polyomino chains based on segments in terms of total irregularity. We can find a sequence for all polyomino chains concerning this graph invariant by defining a non-decreasing function. | ||
