最优过程

The penalty optimal brain surgeon is a post-training algorithm and it has extreme high complexity. The OBS oriented compute model implemented neural network training and OBS pruning simultaneously, by taking the OBS pruning case as a penalty term of neural network objective functions based on optimized structure of the regularization method included in the neural network training process. It both maintained the OBS's accuracy and had regularization method's high efficiency. Raised the generalization of neural network model.

The problem has been studied from two sides, firstly, from the viewpoint of applicability, based on the development strategic objectives of the oil company, with the aim to unify the exploration and extraction decisions of the resources in an integrated framework, and integrate the macro economic and technical objectives with micro economic and technical models of an oil well, an integrated non-linear dynamic optimal control model has been constructed, the objective is the benefit maximum of the exploration and extraction of the resources, and the optimalstrategies are obtained by changing the problem into a non-linear mathematical programming problem, on the other hand, from the more macro level, based on the analysis of the characteristics of the exploration and extraction activities of oil and gas resources, a conclusion is easily deduced that the procedure is full of randomicity, then discovering procedure of oil deposit is proved to be a Poisson process, and the reserves process is a supermartingale process, so the model of exploration discovery rate and the reserves model could be constructed.

其次从相对更宏观的层次上，通过对油气资源勘探与开发的特点分析，认为具有很强的随机性，证明了勘探活动发现油气藏的过程为一泊松过程，所发现的油气藏储量为一上鞅过程，在此基础上，建立了油气藏勘探发现率模型及储量模型，在油气价格服从几何布朗运动条件下，以油气开采收益最大化为目标，建立了一个油气资源勘探与开发的随机最优控制模型，采用动态规划方法得到了值函数的HJB方程，并针对方程的特点，以及方程及其变量所对应的经济学意义，对最优策略的求解进行了一些讨论。

This paper is based on "Trilemma" which is induced from MF model. In order to overcome MF models inherent defects, this paper constructs a static model headed by government on choice of optimum exchange rate regime. Through the analysis of the model we can see that the choice of exchange rate regime is a dynamic process should be decided in real situation. No single exchange rate regime is right for all countries or at all time. Under certain condition intermediate regime may be the optimum one, but the possibility will decrease with the increase of international capital flow.

本文从蒙代尔——弗莱明模型精炼出的"三元悖论"出发，为了克服其内在的缺陷，构建了一个政府主导的静态最优汇率制度选择模型，模型分析表明：汇率制度选择是一个动态的相机决策过程，没有哪一种汇率制度对所有国家或某一国的所有时期都适合；在一定条件下，中间汇率制度可能是最优汇率制度，但是其可选择的区间随着资本流动程度的加大而缩小，最终最优汇率制度将内生的向两极分化。

It suggests that thepace of proceeding reform should be discretionally adjusted according to social acceptance. The best way is to stick reform intentions to the optimal social acceptance. But the optimal social acceptance also varies with economic growth rate and macroeconomic environment. In searching for the optimal socialacceptance, gradual proceeding is better than radical one. It concludes that the higher growth rate and better macroeconomic environment is, the lower optimal social acceptance is acquired, and the stronger intension can we engage.

作者认为，改革推进的快慢应根据社会的可承受程度&相机抉择&，最好是将改革力度控制在最优的社会可承受程度上不变；改革的最优社会可承受程度也不是一成不变的，它因经济发展速度和其他宏观环境的不同而有所不同，在&寻找&改革的社会最优可承受程度的过程中，&渐进&的改革方式好于&激进&的方式；经济发展速度越快，宏观环境越好，改革所要求的最优社会可承受程度越低，改革的力度就可以越大，经济发展有助于改革的推进。
