Computer software is the crystallization of human wisdom. It represents advanced production technology, as well as the expression of ideas and methods of creators. Topological index is the most popular and important in the study of chemical graph theory. According to the linear, unbranched, saturated multi-spiral compound, the simple molecular structure diagram defines the “polygonal chain”. Secondly, the multi-angle chain is studied. The extremum problem of the topological index; at the same time, the multi-angle chain is sorted about the topological index.

Research on the Extreme Value Problem of Topological Index of Polygonal Chain Based on Computer Software Analysis
