该方法的外迭代为经典牛顿法,内迭代为用GMRES法不精确求解雅可比方程。
The outer iteration of this method is the classical Newton method, and the inner iteration is using GMRES to solve Jacobi equations inexactly.
如果您要在整个迭代期间都保持对集合的锁,那么其他的线程就会在锁外停留很长的一段时间,等待解锁。
If you are going to hold the lock on the collection during an entire iteration, then other threads may be stalled waiting for the collection lock for a long time.
但是,一些用户故事要比预期的难,这就意味着一些故事要被挪到下个迭代周期中完成,或者完外被排除在发布中。
But some stories will be harder than anticipated, which means that some work will need to be moved into later iterations or out of the release altogether.
