For example, in the factoring problem, the instances are the integers n, and solutions are prime numbers p that are the nontrivial prime factors of n. An example of a computational problem without a solution is the Halting problem. Computational problems are one of the main objects of study in theoretical computer science.
If the second node is not 0, that is, not a ground: Y22 is summed into the m x m node in the diagonal, where m is the node that the second pin, pin 2, is attached to. Y12 is summed into the n x m node location; Y21 is summed into the m x n node location; The table below shows the Chebyshev element 2x2 Y parameters summed in at the appropriate ...
In computational complexity theory, a problem refers to the abstract question to be solved. In contrast, an instance of this problem is a rather concrete utterance, which can serve as the input for a decision problem. For example, consider the problem of primality testing. The instance is a number (e.g., 15) and the solution is "yes" if the ...
This example program, written in the C programming language, is an example of the Illinois algorithm. To find the positive number x where cos( x ) = x 3 , the equation is transformed into a root-finding form f ( x ) = cos( x ) − x 3 = 0 .
A small signal model consists of a small signal (having zero average value, for example a sinusoid, but any AC signal could be used) superimposed on a bias signal (or superimposed on a DC constant signal) such that the sum of the small signal plus the bias signal gives the total signal which is exactly equal to the original (large) signal to be ...
The travelling purchaser problem, the vehicle routing problem and the ring star problem [1] are three generalizations of TSP. The decision version of the TSP (where given a length L , the task is to decide whether the graph has a tour whose length is at most L ) belongs to the class of NP-complete problems.
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
The second step is discretization, where the weak form is discretized in a finite-dimensional space. After this second step, we have concrete formulae for a large but finite-dimensional linear problem whose solution will approximately solve the original BVP. This finite-dimensional problem is then implemented on a computer.
