Best and worst cases - Wikipedia, the free encyclopedia Worst case performance analysis is often easier to do than "average case" performance. In computer science, best and worst cases in a given algorithm express what the resource usage is at least and at most, respectively. Linear search on an array has a worst-case performance O(n), when the algorithm has to check every element, but the average running time is O(n/2), when the item to be found is around the middle of an array. en.wikipedia.org /wiki/Worst-case_performance

GO! OS :: PERFORMANCE RESULTS No average-case timings are given, because what exactly constitutes the average-case depends on Go!'s use; assuming high cache hit rates and branch prediction success, the best-case can be assumed to be the average case. Without this stability, the impressive performance results would be meaningless, since bug-fixes would likely adversely affect performance. This page gives results of performance experiments performed on Go! goos.sourceforge.net /performance.php

ARCNET ARCNET has slightly lower best-case performance, but is much more predictable. Each approach has its advantages: ARCNET adds a small delay as the message is inspected by each peer, but Ethernet's performance can degrade drastically if too many peers attempt to broadcast at the same time. This is as opposed to the Ethernet model where the messages are broadcast to everyone on the network at the same time. www.sciencedaily.com /encyclopedia/arcnet

The Best Case for ESP? (Generation sXeptic) Bem is correct in pointing out these comparisons, but drawing analogies to other cases in the history of science do not offer arguments for the existence of psi, but rather offer an argument to keep an open and skeptical mind. Imagine for a moment that you are recruited to participate in a ganzfeld experiment, one of the world's most exotic laboratory exercises, and touted as the best known method for testing for "psi" ability. Occasionally, however, parapsychological research will break into mainstream academic outlets, as was the case in 1994 when Bem and University of Edinburgh parapsychologist Charles Honorton published "Does Psi Exist? www.csicop.org /genx/ganzfeld

Anime News Network - Review However, with the dub it's more a case of an average performance rising above an awful cast rather than one outstanding performance amidst an already-superb collection of players. As with the Japanese cast, the best performance comes from the actress portraying Utena, Rachael Lillis. The Japanese cast is top-notch, providing convincing, emotional performances all around. www.animenewsnetwork.com /reviews/display.php?id=627

Is the Magic Number 7 Relevant to Web Page Design Since most of the studies reviewed showed significant effects of training on performance, these studies were clearly examining best case performance. Our findings that memory span was a slightly better performance predictor than visual scanning differed from Snowberry et al.’s [15] findings (although these cognitive pretests were not found to be reliably predictive of performance in either study). In fact, detailed error analyses in Snowberry et al.’s [15] study determined that subjects performed less well in the deep structures due to forgetting the target, or because the category labels at the top levels of the deep structures were too general for subjects to remember the correct traversal paths to a target. www.research.microsoft.com /users/marycz/chi981.htm

Reexamining the Cluster Hypothesis: Scatter/Gather on Retrieval Results Furthermore, we have preliminary evidence that they were able to interpret the cluster summary information well enough to select the cluster with the largest number of relevant documents in most cases (although sometimes along with other clusters, since they were not asked specifically to select the best cluster). We found in 31 out of 38 cases, the participants chose the cluster with the largest number of relevant documents (if there was a tie for largest choosing any cluster with this number was counted as choosing the highest). It is interesting to note that the performance for this two-step procedure is similar to that of the one-step procedure if one divides n by five, which indicates that performance is strongly related to cluster size, with 20 to 50 being close to optimal. www.sims.berkeley.edu /~hearst/papers/sg-sigir96/sigir96.html

Political Calculations: Best and Worst Case Stock Market Investing that shows the general trend between investment holding period and the best and worst case performance of the stock market between 1926 and 1992. I used Siegel's data to create the best and worst case, inflation-adjusted, stock market performance formulas below, using various regression techniques available in Microsoft Excel (and some other mathematical manipulation) to come up with the equations: Compared to determining the effective return that an average "investor" can expect to earn from their "investment" in Social Security, working out the best and worst case investment returns from investing in the stock market turned out to be a breeze! politicalcalculations.blogspot.com /2005/01/best-and-worst-case-stock-market.html   (515 words)

Best, worst and average case - Wikipedia, the free encyclopedia Less widely found is best-case performance, but it does have uses, for example knowing the best cases of individual tasks can be used to improve accuracy of an overall worst case analysis. Average performance and worst-case performance are the most used in algorithm analysis. Worst case analysis has similar problems, typically it is impossible to determine the exact worst case scenario. en.wikipedia.org /wiki/Worst-case_performance   (510 words)

Best-case performance - Wikipedia, the free encyclopedia Development and choice of algorithms is rarely based on best-case performance: most academic and commercial enterprises are more interested in improving average performance and worst-case performance. The term best-case performance is used in computer science to describe the way an algorithm behaves under optimal conditions.

Best, worst and average case - Wikipedia, the free encyclopedia In computer science, best, worst and average cases of a given algorithm express what the resource usage is at least, at most and on average, respectively. Average performance and worst-case performance are the most used in algorithm analysis. In real-time systems, the worst case execution time is often of particular concern since it important to know how much time might be needed in the worst case to guarantee the algorithm would always finish on time. en.wikipedia.org /wiki/Worst-case_performance   (652 words)

Approximability and Nonapproximability Results for Minimizing Total Flow Time on a Single Machine The performance guarantee of our approximation algorithm is not far from best possible, as our second, negative result demonstrates: Unless P=NP, no polynomial-time approximation algorithm for minimum total flow time can have a worst-case performance guarantee of $O(n^{1/2-\eps})$ for any $\eps>0$. This problem is well known to be NP-complete, and the best polynomial-time approximation algorithms constructed so far had (more or less trivial) worst-case performance guarantees of O(n). In this paper, we present one positive and one negative result on polynomial-time approximations for the minimum total flow time problem: The positive result is the first approximation algorithm with a sublinear worst-case performance guarantee of $O(\sqrt{n})$. epubs.siam.org /sam-bin/dbq/article/30577   (234 words)

Pattern Matching For a text of length n and a fixed pattern of length m the best performance of the algorithm is n/m and the worst case is n*m. For text of length n and pattern of length m, its average and best case running time is O(n) (meaning proportional to n), but the worst case scenario is O(n*m), which is one of the reasons why it is not widely used. The word 'suffix' is used in this case to refer to the fact that the trie contains all of the suffixes of a given block of text (perhaps a viral genome.) www.softpanorama.org /Algorithms/pattern_matching.shtml   (5525 words)

Grammy Award Information - TextSheet.com Best Pop Performance by a Duo or Group with Vocal The awards ceremony features performances by prominent artists, and some of the more prominent Grammys are presented in a widely-viewed televised ceremony. Like the Oscars, the Grammys, currently with a total of 101 categories within 28 fields of music (such as pop, gospel, rap), are voted by peers - in this case voting members of the Recording Academy. www.shopping.top5miami.com /encyclopedia/g/gr/grammy_award.html   (5525 words)

sort It's O(n log n) in comparisons as well (worst case), best case of about half of that for basically presorted data, no data needs to be copied (only pointer changes) and you can combine sorting one sublist with scanning for the head of the next sublist, making the stuff pretty efficient. worst case comparisons are merely ceil(lg n) n - 2^(ceil(lg n)) + 1, which for powers of 2 becomes 1-n+n lg n, which beats quicksort's average cases for bigger n. Counting Sort (average and worst case behavior O(n)) Considerations: If you have a long key or a small data set, ACM 347 will probably be fastest. www.math.niu.edu /~rusin/papers/known-math/96/sort   (1008 words)

Assessment of True Worst Case Circuit Performance Under Interconnect Parameter Variations Unlike device variations, which can be captured by worst/best case corner points, the effects of interconnect variations are context-dependent, which makes it difficult to capture the true worst-case timing performance. @inproceedings{AcarNassifLiuPileggi2000, author = {Emrah Acar, Sani R. Nassif, Ying Liu and Lawrence T. Pileggi}, title = {Assessment of True Worst Case Circuit Performance Under Interconnect Parameter Variations}, booktitle = {TAU 2000}, month = {December}, year = {2000}, URL = {http://www.gigascale.org/pubs/22.html} } This paper discusses an efficient method to explore the extreme values of performance metrics and the specific parameters that will cause these extreme performances. www.gigascale.org /pubs/22.html   (306 words)

Sequential Software Engineering Methodology If a solution exists, and the sequential software engineering methodology finds the solution, the best case performance is O(N), the worst case performance is O(N), while the average case performance is O(N) where N is the total number of steps in the environment. Corollary 2.3 (Sequential: Average Case) The average case performance of the sequential software engineering methodology is O(N) where N is the size of the space. Corollary 2.2 (Sequential: Worst Case) The worst case performance of the sequential software engineering methodology is O(N) where N is the size of the space. www-db.stanford.edu /~burback/watersluice/node78.html   (659 words)

THEMISATHENA.INFO: Bonnie Raitt Short of experiencing Bonnie Raitt live on stage, "Road Tested" is the best evidence why rock and blues music, particularly when performed by an artist with such an unmatched passion for her work and skill as a guitar player as is Raitt, is a vastly different experience than listening to a studio album. The album's opening title track is perhaps the best expression of that feeling, with its relaxed, slightly uptempo blues rhythm, its slide guitar solos, the "live-in-the-studio" sound of its vocals, and its background horn arrangements (by Bonnie Raitt herself), subtly framing her voice without ever getting in the way. But just in case you forget where it all began for the multiple Grammy Award winner of so many years later, go back and listen to this album and to Bonnie Raitt's self-titled debut, and let their youthful, upbeat charm work on you. www.themisathena.info /music/raitt1.html   (1749 words)

CS332 Project 1 : Empirical Optimization of Sorting Finally, you will compare the best, worst and average case performance of the optimized versions of quick sort and merge sort to see if the optimization was effective. You should give a best, worst and average case analysis of the number of comparisons and the number of exchanges for each algorithm (or an every-case analysis if appropriate). The recursive cases of the quick sort and merge sort algorithms are fairly complex and of course require recursive calls to implement. www.dickinson.edu /~ziantzl/cs332/project/proj1.html   (2325 words)
