About suboptimal solutions to the problem of identifying of special programmable devices (sensors) and flows control

We are considering the current applied problem of constructing suboptimal solutions to the estimating a homogeneous flow in a bidirectional network. We consider a problem of constructing the suboptimal solution for the bidirectional network. We guarantee that the network is fully monitored if the sensor location if special programmable devices (sensors) are installed in the nodes with unknown external flow. We give an example of constructing a suboptimal solution when installing special programmable devices (sensors) in nodes with variable external flow.
