Characteristic valueknowledge point: "Singular matrix" The judgment matrix is not a matrix (the equal number of rows and columns). If the number of rows and columns is not equal, then the singular matrix and the non-singular matrix are not. Look at the determinant of matrices | a| is equal to 0, if equal to 0, the matrix A is a singular matrix, if not equal to 0, the matrix A is a non-singular matrix. If | A|≠0 The matrix A is reversible, the invertible matrix

meaning and specific feelings, and highlight the advantages. Types of colors in design There are two different color systems, and the use of both depends on what you design. RGB is the color system of the three basic colors "red, green, blue" English abbreviation, these three basic colors are the three primary colors of light. RGB is used on TV computer screens and on any type of screen. CMYK is "cyan, magenta, yellow, black," the English abbreviation, these colors are the prima

named, which expungeStaleEntries() Map is called in most operations, which removes all invalid references in the reference queue and deletes the associated mappings. expungeStaleEntries()a possible implementation is shown in Listing 7. The type used to store the key-value mappings is Entry extended WeakReference , so when the expungeStaleEntries() next invalid weak reference is requested, it gets one Entry . It is more efficient to use a reference queue instead of a regular scan of the content,

topological sorting (topological sort)topological ordering is a sort of a directed acyclic graph (DAG) vertex, which allows you to have a forward path to V if there is a U, v. the order in which you are in front of v. Topological ordering is a complete sequence (called topological order) that is obtained by a partial order (partical order). Partial order satisfies reflexivity, anti-symmetry, The order of transitivity.The idea of topological sequencing is simple, that is, each time you find a poi

Concurrenthashmap is part of Doug Lea's Util.concurrent package, which offers a higher degree of concurrency than Hashtable or synchronizedmap. Also, for most successful get () operations, it tries to avoid a complete lock, and the result is a very good throughput for concurrent applications. This month, Briangoetz carefully analyzed the code of the Concurrenthashmap and explored how Doug Lea achieved such a remarkable result without losing thread safety. In the July issue of Java

Many programmers do not use fixed-point or floating-point numbers throughout their development careers, with the possible exception being used occasionally in timing tests or benchmarking programs. The Java language and class libraries support two types of ―ieee 754 floating-point (float and double, wrapper class (wrapper class) for float and double), and arbitrary-precision decimals (java.math.BigDecimal). In this month's Java theory and practice, Br

Observer mode is common in Swing development, and is useful for eliminating the coupling of components in scenarios other than GUI applications. However, there are still some common flaws in the registration and invocation of listeners. In this period of Java theory and practice, Java expert Brian Goetz offers some good advice on how to make a good listener and how to be friendly to your listeners.

The Java language provides flexible, seemingly simple threading capabilities that make it easy to use multithreading in your applications. However, concurrent programming in Java applications is more complex than it seems: in Java programs, there are subtle (and perhaps not subtle) ways to create data contention (race) and concurrency problems. In this Java theory and Practice, Brian explores a common thread hazard: Allow this reference to escape duri

value is 263-1, which is about 9.2x1018. Currently, it is possible to create 108 objects per second, which means that a program has to run for about 3,000 years before a long object counter overflows. Even in the face of hardware speed improvements, a long object counter should be sufficient to handle the foreseeable future.Also note that the Create count policy in this puzzle is not thread-safe. If multiple threads can create objects in parallel, the code that increments the counter and the co

connected components. the necessary and sufficient condition of the binary graph is that there is no odd circle, which can be obviously obtained: if a two-connected component is a binary graph, then the inside point must not be on the odd circle. If a two-connected component is not a binary graph, will the dots in it be on the odd circle?The answer is certain in the odd circle, the first two connected components is not a binary map, then there must be a singular ring C. There are two states fo

thought, each time the shortest current distance of the node, think it is the most short-circuit is already determined. It can be proved that this is the right thing to do. This is why the optimized version of the Dijkstra algorithm is used for priority_queue reasons.So back to the topic, how to solve the short-circuit? If we want to solve the short-circuit of the starting S to the end point T, then there are two possible cases: (1) The Shortest Path +d (u,t) of the beginning S to a vertex u. (

question of the topic, we just need to run the diagram out of the bare Tarjan.However, the second question is obviously not so simple, the topic asks us to find the capacity for n-1 of the Unicom block, here to note:cannot be calculated directly, because your diagram has been destroyed by the first question.
