推理机的计时虽然我们将推理机描述为程序上松散,但并不意味着在程序上当调用子程序时就放松控制,直到被调用子程序完成功能。当一个启发框架必须评价其状态时,则需要其它变量的状态,这些变量在当前状态下不能被获得,它便激活这些变量并且立即终止。仅在终止前,它 Inference Engine Timing Although we describe reasoning machines as loosely-knit procedures, this does not mean that control is loosened when the subroutine is called on the program until the called subroutine completes the function. When a heuristic framework has to evaluate its state, it needs the state of other variables that can not be obtained in the current state, it activates these variables and terminates immediately. It’s only before termination
