of a [I] + B [J] is reduced. That is to say, it originally does not belong to an equal subgraph, And now it may have entered an equal subgraph, thus expanding the equal subgraph.
The problem now is to evaluate the value of D. To ensure that a [I] + B [J]> = W [I, j] is always valid, and at least one edge enters an equal subgraph, D should be equal:
Min {A [I] + B [J]-W [I, j] | Xi is in the staggered tree, Yi is not in the staggered tree }. The above is the basic idea of the KM algorithm. H

The requirement for the following is Toffset_in_before-(tdata + Tsetup-tclock) > 0, which in fact corresponds to slack greater than 0.

Tsetup = intrinsic Flip Flop setup time

The purpose of the Custom-explainer-videos commentary video is to illustrate how a product or service works. Visitors may still not know how to operate the product after they have browsed through a series of features. A visual video can be one by one illustrative in just a few minutes and covers all the important content. The key thing is that people like to watch videos rather than read articles. They can easily see what you want to express from the video.

DNS is used whenever you use the Internet. Every time you send an email or surf the internet, you must rely on DNS. DNS is responsible for the ing between host names and interconnected network addresses, which is handled by computers. If the connection to the DNS server is delayed, or if the DNS server resolves an address too long, the access will be delayed. If domain name resolution can be accelerated in some way, the speed of surfing the Internet can be accelerated. The following describes a
