Abstract
We consider the problem of quickest detection of abrupt changes for pr ocesses that are not necessarily independent and identically distribut ed (i.i.d.) before and after the change. By making a very simple obser vation that applies to most well-known optimum stopping times develope d for this problem (in particular CUSUM and Shiryayev-Roberts stopping rule) we show that their optimality can be easily extended to more ge neral processes than the usual i.i.d. case.
