...点来决定何时哪个站台可以开始传送资料的机制.PCF是属于免竞争式(contention free, CF)方法,站台的传送具有时限性(time bounded).因此在使用上也不会发生讯框碰撞(需要站台能遵守协定规则且没有干扰源以及隐藏点等问题)的情形.

Bounded Rationality is the idea that individual decision making is limited by personal information, cognitive limitations, and time constraints.
根据有限理性的观点,个人作出的决策会受到个人知识、认知局限和时间的制约。
Try relaxing the value of each bounded constraint one at a time, solve the modified problem, and see what happens to the optimal value of the objective function.
一次只尝试放松每个边界约束一个单位,解决修改后的问题,看一下目标函数的优化值发生了什么变化。
The lifetime is most likely bounded by an expiration time, especially in a distributed environment where invalidating a token can be quite a challenge.
很可能通过一个过期时间来界定生存期,特别是在分布式环境中,要使一个令牌失效是非常困难的。
Remember last time, I said that there's different kinds of complexity in our code, and I suggested for simple branching programs, the amount of time it takes to run that program is, in essence, bounded by the number of instructions, because you only execute each instruction at most once.
但是这里有个很重要的点,记得上节课,我提过在我们的代码中,有不同种类的复杂度,而且我还说了对于简单的分支程序,运行这种程序需要的总体时间,大体上,是和指令的数目相关的,因为每个指令只会被执行最多一次。
