Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2021 Limited precision floating point computer implementations of large polynomial arithmetic expressions are nonlinear and dissipative. They are not reversible (irreversible, lack conservation), lose information, and so are robust to perturbations (anti-fragile) and resilient to fluctuations.

On the relation between dissipativity and discounted dissipativity [PDF]
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017 In this paper, we consider a recently introduced notion of discounted strict dissipativity which is of interest, e.g., in the context of discounted optimal control and economic model predictive control. We consider the question whether (standard) strict dissipativity implies discounted strict dissipativity for discounting factors close enough to one ...

Fluctuation-dissipation relations in driven dissipative systems [PDF]
Physical Review E, 2006 Exact theoretical results for the violation of time dependent fluctuation-dissipation relations in driven dissipative systems are presented. The ratio of correlation to delayed response in the stochastic model introduced in [Phys. Rev. Lett. 93, 240601 (2004)] is shown to depend on measurement time.

Power dissipation in division [PDF]
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008 A few classes of algorithms to implement division in hardware have been used over the years: division by digit-recurrence, by reciprocal approximation by iterative methods and by polynomial approximation. Due to the differences in the algorithms, a comparison among their implementation in terms of performance and precision is sometimes hard to make. In

Complex Systems, 2022 Large arithmetic expressions are dissipative: they lose information and are robust to perturbations. Lack of conservation gives resilience to fluctuations. The limited precision of floating point and the mixture of linear and nonlinear operations make such functions anti-fragile and give a largely stable locally flat plateau a rich fitness landscape ...

Dissipation enhancement by mixing* [PDF]
Nonlinearity, 2019 Abstract We quantitatively study the interaction between diffusion and mixing in both the continuous, and discrete time setting. In discrete time, we consider a mixing dynamical system interposed with diffusion. In continuous time, we consider the advection diffusion equation where the advecting vector field is assumed to be ...

A New Criterion Beyond Divergence for Determining the Dissipation of a System: Dissipative Power
Frontiers in Physics, 2021 Divergence is usually used to determine the dissipation of a dynamical system, but some researchers have noticed that it can lead to elusive contradictions. In this article, a criterion, dissipative power, beyond divergence for judging the dissipation of

Dissipation in Lagrangian Formalism
Entropy, 2020 In this paper, we present a method by which it is possible to describe a dissipative system (that is modeled by a linear differential equation) in Lagrangian formalism, without the trouble of finding the proper way to model the environment. The concept of the presented method is to create a function that generates the measurable physical quantity ...
