ABSTRACT Generally, the majority of achievements on privacy preservation consensus always anchor that number interacting agents is permanent. Nevertheless, this overly restrictive in many multi‐agent systems (MAS) applications where agent removal or joining may arise at any operational instant. In light this, current article studies privacy‐preserving problem open MAS. To achieve we propose an state‐decomposition‐based algorithm not only assures but also achieves initial states, despite...

Potato is an important crop that can be used both as grain and vegetable in northern China. However, the continuous cropping system of potato has led to a sharp decline its yield quality. As one effective strategies alleviate obstacle, rotation received extensive attention agricultural practices. On this basis, we have conducted in-depth exploration effects potato-maize on structure diversity soil microbial community, aiming analyze internal correlation mechanism between community quality...
