If we can extract a schema from a graph efficiently, we can take advantage of the extracted schema for query optimization, structure browsing, and so on. In this paper, we consider extracting schemas from large graphs by using utility function . Although reasonable schemas can be extracted by ...

An entire utility function can be graphically represented by an indifference curve map, where several indifference curves correspond to different levels of utility. In the graph below, there are three different indifference curves, labeled A, B, and C. The farther from the origin, the greater uti...
In Exercises, use a graphing utility to graph each function in the same viewing window. Describe how the graph of each function is related to the graph of y=x^2.(1)y=x^2(2)y=-2x^2(3)y=x^2+2(4)y=(x+5)^2 相关知识点: ...
