Presents new types of Pythagorean soft fuzzy graphs to facilitate decision-making in team selection.
In this paper, we introduced various types of new notations, including Pythagorean soft fuzzy graphs, complete Pythagorean soft fuzzy graphs, and strong Pythagorean soft fuzzy graphs. Then, we defined some operations on Pythagorean soft fuzzy graphs, such as union, intersection and different types of multiplication. After that, we extended the concept of density in Pythagorean soft fuzzy graphs and posed a decision-making problem for selecting a harmonious work team and a very close work ethic. Then, we selected the most optimal team by using the concept of density in Pythagorean soft fuzzy graphs
