The X end is in the staggered tree, and the Y end is not in the edge (I, j) of the staggered tree. The value 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 to mi

To ensure that a [I] + B [J]> = W (I, j) is always valid, and at least one edge is added to an equal subgraph, D = min {A [I] + B [J]-W (I, j)}, I is in the staggered tree, J is not in the staggered tree
Time Complexity:You need to find the O (n) Increment path. You need to modify the O (n) Increment path at most. During each increment, the enumeration edge is used to evaluate the D value. The complexity is O (n2

Brief introduction
Supervisor is a process management tool in the *NIX environment that transforms the foreground process into a daemon and restarts automatically when the process exits unexpectedly.The Supervisor-event-listener listens for a process exception exit event and sends a not
relaxation until the queue is empty.The expected time complexity O (ke), where k is the average number of incoming teams for all vertices, can prove that K is generally less than or equal to 2.Implementation method:Set up a queue that initially has only a starting point in the queue, and then establish a table that records the shortest path from the starting point to all points (the initial value of the table is assigned a maximum value, and the point to his own path is assigned to 0).

In addition to fully cross-platform implementations, there are also the following changes and enhancements:
The dnx command is simplified. You do not need to enter the "point ".
You can use the previous app. config file when using the full version of. NET Framework.
Optimized MVC functions in Razor, ViewComponent, and TagHelper.

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
