An asymptotic optimal solution to this problem, which has been proposed in previous works, leads to the number of arithmetical operations at time t which grows to infinity with t. Moreover, the proposed criterion of optimality does not impose a constraint on the probability of false isolation when the change time t/sub 0/>1. In this paper we propose another more realistic criterion, establish a new simple recursive change detection/isolation algorithm and investigate its statistical properties. This algorithm can be recommended for on-line implementations. %G English %L hal-02290451 %U https://utt.hal.science/hal-02290451 %~ CNRS %~ UNIV-TROYES %~ UTT %~ UTT-LIST3N %~ LM2S-UTT
