An Efficient Approach To Control Congestion
A key problem in communication networks is to understand how to control congestion and maintain a normal and efficient functioning of the networks. Zonghua Liu et al. studied the network congestion and get the result that congestions are more likely to take place at the nodes with high degrees in networks (See Fig. 8), and an efficient approach of selectively enhancing the message-process capability of a small fraction(e.g. 3%) of nodes is shown to perform just as well as enhancing the capability of all nodes.(See Fig. 9)

“An efficient and valuable man does what he can, whether the community pay him for it or not. The inefficient offer their inefficiency to the highest bidder, and are forever expecting to be put into office. One would suppose that they were rarely disappointed.”

“Let me approach at least, and touch thy hand.
[Samson:] Not for thy life, lest fierce remembrance wake
My sudden rage to tear thee joint by joint.
At distance I forgive thee, go with that;
Bewail thy falsehood, and the pious works
It hath brought forth to make thee memorable
Among illustrious women, faithful wives:
Cherish thy hast’n’d widowhood with the gold
Of Matrimonial treason: so farewel.”
—John Milton (1608–1674)
“The general fact is that the most effective way of utilizing human energy is through an organized rivalry, which by specialization and social control is, at the same time, organized co-operation.”
—Charles Horton Cooley (1864–1929)
“In Western Europe people perish from the congestion and stifling closeness, but with us it is from the spaciousness.... The expanses are so great that the little man hasn’t the resources to orient himself.... This is what I think about Russian suicides.”
—Anton Pavlovich Chekhov (1860–1904)
