The efficient use of energy is a critical aspect in Wireless Sensor Networks (WSNs) to
prolong the network's lifespan. Investigating routing in WSNs requires considering the …

Given an edge-weighted graph G=(V, E) with vertex set V and edge set E, we study in this
paper the following related balanced tree structure problems in G. The first problem, called …

In the paper, a new method is introduced for optimally solve the problem of the layout and
component size determination of sewer network. Simultaneously Layout and component …

Efficient utilization of energy is a crucial concern in Wireless Sensor Networks (WSNs) to
increase the network's longevity. However, it is impossible to investigate routing without …

Hungarian method is a classical method for solving assignment problems. It also can be
widely used in other problems, such as matching problem. This paper researches its …

The optimal design of sewer network includes two subproblems:(1) finding the feasible
sewer layouts and (2) optimal design of sewer layout components. The topic of sewer …
