Hybrid soft computing models applied to graph theory Rough Fuzzy Graphs Fuzzy Rough Graphs Intuitionistic Fuzzy Rough Graphs Fuzzy Soft Graphs Intuitionistic Fuzzy Soft Graphs Soft Rough Fuzzy Graphs Bipolar Fuzzy Soft Graphs Soft Rough Neutrosophic Influence Graphs This book describes a set of hybrid fuzzy models showing how to use them to deal with incomplete and or vague information in different kind of decision making problems. Based on the authors’ research it offers a concise introduction to important models ranging from rough fuzzy digraphs and intuitionistic fuzzy rough models to bipolar fuzzy soft graphs and neutrosophic graphs explaining how to construct them. For each method applications to different multi attribute multi criteria decision making problems are presented and discussed. The book which addresses computer scientists mathematicians and social scientists is intended as concise yet complete guide to basic tools for constructing hybrid intelligent models for dealing with some interesting real world problems. It is also expected to stimulate readers’ creativity thus offering a source of inspiration for future research
