    Throughout natural and engineered systems, questions about stability always arise. Will a power network avoid blackouts? Will the Internet avoid traffic congestion? Will a species population survive? Engineered systems now have features comparable to living systems, namely massive scale, high degrees of nonlinearity, uncertainty and heterogeneity. Such systems are summarized as being complex. An i... View full abstract»
