Chinese postman problem. A worked example of an undirected Chinese postman problem: 1. Each street must be traversed at least once, starting and ending at the post office at A. 2. Four vertices with odd degree (orange) are found on its equivalent graph. 3. The pairing with the lowest total length is found. 4.
The XY problem obscures the real issues and may even introduce secondary problems that lead to miscommunication, resource mismanagement, and sub-par solutions. The solution for the support personnel is to ask probing questions as to why the information is needed in order to identify the root problem Y and redirect the end user away from an ...
If the status code indicated a problem, the user agent might display the reason phrase to the user to provide further information about the nature of the problem. The standard also allows the user agent to attempt to interpret the reason phrase , though this might be unwise since the standard explicitly specifies that status codes are machine ...
The primary applications are computational fluid dynamics and aerodynamic shape optimization, [2] but has been extended to treat more general equations such as electrodynamics and chemically reacting flows. SU2 supports continuous and discrete adjoint for calculating the sensitivities/gradients of a scalar field.
Numerical stability. In the mathematical subfield of numerical analysis, numerical stability is a generally desirable property of numerical algorithms. The precise definition of stability depends on the context. One is numerical linear algebra and the other is algorithms for solving ordinary and partial differential equations by discrete ...
In applied mathematics, the maximum generalized assignment problem is a problem in combinatorial optimization. This problem is a generalization of the assignment problem in which both tasks and agents have a size. Moreover, the size of each task might vary from one agent to the other. This problem in its most general form is as follows: There ...
Michael Schumacher ( German: [ˈmɪçaːʔeːl ˈʃuːmaxɐ] ⓘ; born 3 January 1969) is a German former racing driver who competed in Formula One for Jordan, Benetton, Ferrari, and Mercedes. Schumacher has a joint-record seven World Drivers' Championship titles (tied with Lewis Hamilton ); at the time of his retirement from the sport in 2012 ...
In computability theory, the halting problem is the problem of determining, from a description of an arbitrary computer program and an input, whether the program will finish running, or continue to run forever. The halting problem is undecidable, meaning that no general algorithm exists that solves the halting problem for all possible program ...
