We investigate whether the equilibrium time-averaged state of a self-organizing system with many internal degrees of freedom, 2D-daisyworld, can be described by optimizing a single quantity. Unlike physical systems where a principle of maximum energy production has been observed, daisyworld follows evolutionary dynamics rather than Hamiltonian dynamics. We find that this is sufficient to invalidate the maximum entropy production principle, finding instead a different principle, that the system self-organizes to a state which maximizes the amount of life.
我们研究了具有许多内部自由度的自组织系统——二维雏菊世界的平衡时间平均状态是否可以通过优化单个量来描述。与观察到最大能量产生原理的物理系统不同,雏菊世界遵循进化动力学而非哈密顿动力学。我们发现这足以使最大熵产生原理无效,取而代之的是发现了一个不同的原理,即系统自组织到一个使生命量最大化的状态。
