Deformation of the shortest path.
The meaning of the question is to give you the probability that the road will not be caught. It is required to find the maximum probability of not being caught when the destination is reached.
Set the initial DIS [] to 1. The remaining values are 0. Find the maximum value.

Yesterday, a student who planned a city in South University asked me on Sina Weibo
He converted JSON data into a vector image. I have never heard of this conversion before. I went to the website and checked it, the discovery of Chicago really put the city planning data on GitHub, see here: http://thechangelog.com/the-city-of-chicago-is-on-github/
Select one of them at will. Here I select bikeRoute
Yesterday, a student at the Southern University of the city planning on Sina Weibo @ I,
By that he means to convert the JSON data to vector graphics, I didn't hear a good switch before, and I saw that Chicago really put the city planning data on the GitHub, see here: http://thechangelog.com/ the-city-of-chicago-is-on-github/
Choose one of them at random, I choose bike here.Routes in
The main idea, give the N nodes, M-edge, each edge of the weight of the line from the edge of the police are not caught by the probability, asked from Node A to Node B is not caught the maximum probability.
Floyd deformation, simply change the
distributions, select the hash algorithm. The queue algorithm can only store records with a fixed length. In the case of high concurrent processing, the queue algorithm is more efficient. In other cases, select the recno algorithm, the recno algorithm stores data in a flat file format.

The installed files are stored in the/usr/local/BerkeleyDB.5.3 directory of the system by default. To use the files in the programming environment, you need to use them in/etc/ld. so. add/usr/local/BerkeleyDB.5.3/lib to the conf file so that your program can find the library file correctly and finally run the ldconfig command to update your system.

The program I saw on the blog of small A (angel) was very simple and powerful! Haha !~ PHP is used for implementation. I added code comments on the basis of his writing, so that it is easy for friends who do not understand PHP to understand. I don't need to talk about anything nonsense and go to the code!

Hint related to the table connection method1, Use_mergeUse_merge is a hint for multiple target tables, and it means that the optimizer will concatenate multiple tables that we specify as the driven table with other tables or result sets. The target table specified in Use_merge hint should be the driven table of the sort merge connection, and if the specified table is not a driven table for the sort merge connection, then Oracle either ignores the hint or ignores the table.The format is as follow
members of the DG configuration must be configured with a remote logon password file, and each physical standby database must have the latest copy of the password file of the master database.
