The symmetric division degree (SDD) index is one the ۱۴۸ discrete Adriatic indices,introduced by Vukicevi´c et al. as a remarkable predictor of total surface area of polychlorobiphenyls.The SDD index has already been proved a valuable index in the QSPR/QSAR studies. This paper isessentially a survey of known results about bounds for SDD index of graphs.
