The Maximum Entropy Production Principle: Its Theoretical Foundations and Applications to the Earth System [PDF]

open access: yes, 2010
The Maximum Entropy Production (MEP) principle has been remarkably successful in producing accurate predictions for non-equilibrium states. We argue that this is because the MEP principle is an effective inference procedure that produces the best ...

Pontryagin Maximum Principle for Distributed-Order Fractional Systems

open access: yesMathematics, 2021
We consider distributed-order non-local fractional optimal control problems with controls taking values on a closed set and prove a strong necessary optimality condition of Pontryagin type.

A maximum principle related to volume growth and applications [PDF]

open access: yesAnnali di Matematica Pura ed Applicata, 2020
In this paper, we derive a new form of maximum principle for smooth functions on a complete noncompact Riemannian manifold M for which there exists a bounded vector field X such that ⟨∇f,X⟩≥0\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage ...

Maximum principle for discrete-time stochastic optimal control problem and stochastic game

open access: yesMathematical Control and Related Fields, 2021
This paper is first concerned with one kind of discrete-time stochastic optimal control problem with convex control domains, for which necessary condition in the form of Pontryagin's maximum principle and sufficient condition of optimality are derived ...

Maximum Principle Preserving Exponential Time Differencing Schemes for the Nonlocal Allen-Cahn Equation [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2019
The nonlocal Allen--Cahn equation, a generalization of the classic Allen--Cahn equation by replacing the Laplacian with a parameterized nonlocal diffusion operator, satisfies the maximum principle ...

A second-order and nonuniform time-stepping maximum-principle preserving scheme for time-fractional Allen-Cahn equations [PDF]

open access: yesJournal of Computational Physics, 2019
In this work, we present a second-order nonuniform time-stepping scheme for the time-fractional Allen-Cahn equation. We show that the proposed scheme preserves the discrete maximum principle, and by using the convolution structure of consistency error ...

Abolishing the maximum tension principle

open access: yesPhysics Letters B, 2015
We find the series of example theories for which the relativistic limit of maximum tension Fmax=c4/4G represented by the entropic force can be abolished.

Utility Function from Maximum Entropy Principle

open access: yesEntropy, 2006
Recently we used the maximum entropy principle for finding the price density in a multi agent insurance market. The result is similar to what the Buhlmann had obtained by maximizing the utility function.

Sufficient Stochastic Maximum Principle in a Regime-Switching Diffusion Model [PDF]

open access: yes, 2011
We prove a sufficient stochastic maximum principle for the optimal control of a regime-switching diffusion model. We show the connection to dynamic programming and we apply the result to a quadratic loss minimization problem, which can be used to solve a
