People living with HIV/AIDS have always been victims of the most extreme forms of social discrimination. They are stereotyped and stigmatized, and are seen as people outside the 'general population'.In this book The authors use mathematical tools to attempt an understanding of public awareness and attitude towards people living with HIV/AIDS.Here, for the first time, a new model, called n-adaptive fuzzy model, has been introduced. This model has the capacity to analyze the same problem in different ways thereby arriving at various solutions that mirror multiple perspectives.
