智能系统的最经常和最基本工作是满足目标的方法选择.在智能系统中,决策(方法选择)是控制知识的重要内容.选择的标准是使计算费用最小.计算费用包括方法应用费用和方法选择费用.现在,在控制知识中考虑一个数学模型,由此数学模型作出方法选择,使得计算费用最小. The most often and most basic work of intelligent systems is to meet the goal of the choice of method.In the intelligent system, decision-making (method choice) is an important part of controlling knowledge.The choice of the standard is to make the calculation of the cost of the minimum.Calculation of costs including the method of application costs and methods Choosing a Cost Now, consider a mathematical model in control knowledge from which the mathematical model makes the choice of method that minimizes the computational cost.
