The step-size of variable power is decided according to both channel fading characteristics estimated by a Kalman filter and the previous power control instructions recorded by a memory unit.

The immune memory units guarantee this algorithm rapid convergence to global optimum and the uniform crossover operator embody the idea of evolution.

To acquire the optimal solution of the new model,immune algorithm is proposed and improved in three aspects: a memory unit group is introduced to make the algorithm perform on two independent groups parallelly; an adaptive method of exporting vaccines and inoculation is presented;and a chaos operator is implanted to the algorithm for anti-freezing.

Apart from this,there also was a hypothesis concerning the lack of confidence or metamemory deficits in OCD.

The paper paid especial attention to developmental factors(such as memory capacity,knowledge base and metamemory),individule factors(such as IQ and attribution) and external factors(such as instruction conditions) which caused the occurrence of "Utilization Deficiency".

This article reviews the history of metamemory research and points out the problems and the direction of coming research.

In associative Hopfield neural networks, analyzing binary orthogonal memory patterns plays a very important role in studying their storage capacity.
