Highly optimized tolerance: robustness and design in complex systems
Highly optimized tolerance (HOT) is a mechanism that relates evolving structure to power laws in interconnected systems. HOT systems arise where design and evolution create complex systems sharing common features, including (1) high efficiency, performance, and robustness to designed-for uncertainties, (2) hypersensitivity to design flaws and unanticipated perturbations, (3) nongeneric, special...
متن کاملPower law behavior in designed and natural complex systems: self-organized criticality versus highly optimized tolerance
Power law scalings are abundant in natural and man-made complex systems, but the presence of a power law in itself is insufficient to specify the mechanism that generates it. It would be particularly valuable to understand the origin of the power law distribution of electrical blackout size versus frequency in national high-voltage power grids, in order to better moderate blackouts. The concept...
متن کاملNoncooperatively Optimized Tolerance: Decentralized Strategic Optimization in Complex Systems
We introduce noncooperatively optimized tolerance (NOT), a game theoretic generalization of highly optimized tolerance (HOT), which we illustrate in the forest fire framework. As the number of players increases, NOT retains features of HOT, such as robustness and self-dissimilar landscapes, but also develops features of self-organized criticality. The system retains considerable robustness even...
متن کاملEvolutionary dynamics and highly optimized tolerance.
We develop a numerical model of a lattice community based on Highly Optimized Tolerance (HOT), which relates the evolution of complexity to robustness tradeoffs in an uncertain environment. With the model, we explore scenarios for evolution and extinction which are abstractions of processes which are commonly discussed in biological and ecological case studies. These include the effects of diff...
متن کاملWildfires, complexity, and highly optimized tolerance.
Recent, large fires in the western United States have rekindled debates about fire management and the role of natural fire regimes in the resilience of terrestrial ecosystems. This real-world experience parallels debates involving abstract models of forest fires, a central metaphor in complex systems theory. Both real and modeled fire-prone landscapes exhibit roughly power law statistics in fir...
