more than just one side. Conversely, if the augmented path is not found, the current match is the maximum match.
To find the augmented path, there is an augmented path to exchange the unmatched and matching edges of the augmented path, which will make the current maximum number of matches +1. Minimum path overlay for Dag
Definition: In a forward graph, find the least path so that these paths pass through all the points.
The minimum path overlay is divided into minimal disjoint path overlay an
Most basic three
(1) predicate coverage (PC)
Each predicate shocould evaluate to both true and false.
(2) clause coverage (cc)
Each clause in predicate shoshould evaluate to both true and false.
(3) Combinatorial coverage (CBC)
All combinations of clause values shoshould be considered.
Let's use an example to initialize strate the idea.
Suppose we have Java code
1. Independent interval Problems
Find the maximum number of intervals that do not cover each other in N intervals
Sort the ending point, and then select from the interval with the smallest ending point.
2. Coverage Interval
Give a large interval, then give n cells, and find the minimum number of intervals to cover the large interval.
First select the start vertex, then select the maximum ending vertex range of the Start vertex, and so on.

coverage.
The second type of problem is that although a graph is provided on the surface, some nodes in the graph are special. Our task is not to solve this graph, but to address these special points, re-create a new graph G, and then convert G to A bipartite graph to find the maximum path coverage.
For example:

in a chessboard of 2kx2k squares, a square is different from other squares, calling it a special square and calling it a special chessboard. problem: Use 4 different forms of L-shaped dominoes to cover all squares except special squares on a given special chessboard, and any 2 must not overlap. There are 4k cases where special squares appear on the board. Thus, for any k>=0, there are 4k different special chessboard. It is easy to know that in any 2k * 2k chessboard, the number of L-type dominoe
A taxi company has M appointments, and each reservation occupies one line: (for example) a B c d (a, B) indicates the starting point of the reservation. (c, d) indicates the end of the task. The previous time is the start time, and the end time of the task is | a-c | + | B-d | + start time, so for the M booking, how many vehicles can be dispatched at least? Analysis: At first, I thought of the Time Scheduling Problem in the greedy algorithm, but later I found an error. Here we should use the min

Problem description:
In a checkerboard consisting of 2 k × 2 k squares, a square is different from other squares. It is called a special square and a special checkerboard.
In the Board coverage problem, we need to use four different types of L-shaped bone cards in the figure to cover all squares except the special square on the given special board,
And no two L-type dominoes can overlap.
Analysis:
When k> 0, the 2 k × 2 k board is divided into 4 2
