The functions of the above three graphs are, in turn,. We want to use these three functions to fit the true value of Price,price.
Given that these three functions will output one, this output ma

COST value 1. Topology: 2. Configuration and Description: 1. Configure the IP address and ospf protocol of each interface. I used an R0 router to configure a frame relay switch. This helps us better understand frame relay. Note: When R1 and R4 use the FR interface, you can define the interface type ip ospf network broadcast or manually specify the neighbors of the two interfaces. Otherwise, the neighbors may fail. 2. Then we can manually specify the
As a member of the electronics industry chain, both chip designers, producers, testers and users are interested in knowing exactly what parts of a chip the cost is.

The idea of this question is completely self-developed, and I feel quite clever... (Do not spray the ox ...) I have more confidence in building bold images.
The specific idea is to construct a bipartite graph. The Si source and Xi connection points have 1 traffic and the cost is 0. then, when Si can win Xj, the two will be connected to one edge and the
