There is a tradeoff between these two costs l

Conclusions
Continuation Region
Iteration algorithm can be applied to an general l
Markov Chain
Mobile issues registration when it is not where l
it is expected to be
Continuation region tends to move with mobile l
Continuation region tends to increase with l d
Converge to locally optimal, but not globally l
