It is shown that under very weak assumptions the solution exists and is unique and linear in the information.

The time horizon is infinite. In the context of a simple linear quadratic model strategies that may achieve the aforementioned aim are suggested, and several insights and results are discussed.<<ETX>>

It is shown that, under a weak coupling condition, the Projection Algorithm will ensure that the system inputs and outputs remain bounded for all time and that each controller can successfully make the corresponding output tracking error converge to zero.

This model allows static or dynamic allocation of the iterate vector components to processors. It also allows simultaneous updating of the same vector component by multiple processors. Sufficient conditions under which the model of asynchronous iterations converges in the second moment (and in the mean) to the sought solution are provided. For the specialization of the Markov case when the communication delays are independent, identically distributed (i.i.d.), we provide sufficient conditions for convergence in the second moment and necessary and sufficient conditions for convergence in the mean.
