Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...
For example, there is an (()) algorithm for finding minimum spanning trees, where () is the very slowly growing inverse of the Ackermann function, but the best known lower bound is the trivial (). Whether this algorithm is asymptotically optimal is unknown, and would be likely to be hailed as a significant result if it were resolved either way.
Each computable function has an infinite number of different program representations in a given programming language. In the theory of algorithms one often strives to find a program with the smallest complexity for a given computable function and a given complexity measure (such a program could be called optimal). Blum's speedup theorem shows ...
In computer architecture, speedup is a number that measures the relative performance of two systems processing the same problem. More technically, it is the improvement in speed of execution of a task executed on two similar architectures with different resources.
Linear speedup theorem, that the space and time requirements of a Turing machine solving a decision problem can be reduced by a multiplicative constant factor. Blum's speedup theorem , which provides speedup by any computable function (not just linear, as in the previous theorem).
A FedEx contract worker has been busted for allegedly dumping dozens of packages in the woods to avoid working late. Latavion Lewis was arrested after a post office in Bonifay, Florida, received ...
The situation T 1 / T p = p is called perfect linear speedup. [9] An algorithm that exhibits linear speedup is said to be scalable. [6] Analytical expressions for the speedup of many important parallel algorithms are presented in this book. [10] Efficiency is the speedup per processor, S p / p. [6] Parallelism is the ratio T 1 / T ∞. It ...
What does it mean to refinance a mortgage? Refinancing is a process of trading in your current mortgage to another lender for lower rates and better terms than your current loan.
