CentralNotice From Wikipedia, the free encyclopedia Jump to: navigation , search Matrix chain multiplication (or Matrix Chain Ordering Problem, MCOP) is an optimization problem that can be solved using dynamic programming . Given a sequence of matrices, the goal is to find the most efficient way to multiply these matrices . The problem is not actually to perform the multiplications, but merely to decide the sequence of the matrix multiplications involved. We have many options because matrix multiplication is associative . In other words, no matter how we parenthesize the product, the result obtained will remain the same. For example, if we had four matrices A , B , C , and D , we would have: (( AB ) C ) D = (( A ( BC )) D ) = ( AB )( CD ) = A (( BC ) D ) = A ( B ( CD )). However, the order in which we parenthesize the product affects the number of simple arithmetic ...

Well I don't know if this is normal or not but it struck me how come a package only 7MB in size took over 3 hours to compile. My computer can compile larger package (in size) in a more timely manner. Firefox worth 70MB of download but took only 1 hour to compile. Does webkit-gtk took that long for you guys as w...

BDD Kickstart San Francisco CA, 21-23 Apr Docs Blog School Training Cucumber Pro Support Cucumber lets software development teams describe how software should behave in plain text. The text is written in a business-readable domain-specific language and serves as documentation, automated tests and development-aid - all rolled into one format. Cucumber works with Ruby, Java, .NET, Flex or web applications written in any language. It has been translated to over 40 spoken languages. Cucumber also supports more succinct tests in tables - similar to what FIT does. Dig around in the examples and documentation to learn more about Cucumber tables. Cucumber is Aslak Hellesøy's rewrite of RSpec's "Story runner", which was originally written by Dan North. (Which again was a rewrite of his first implementation - RBehave. RBehave was his Ruby port of JBehave). Early versions of the RSpec "Story Runn...

CentralNotice From Wikipedia, the free encyclopedia Jump to: navigation , search The friendship paradox is the phenomenon first observed by the sociologist Scott L. Feld in 1991 that most people have fewer friends than their friends have, on average. [ 1 ] It can be explained as a form of sampling bias in which people with greater numbers of friends have an increased likelihood of being observed among one's own friends. In contradiction to this, most people believe that they have more friends than their friends have. [ 2 ] The same observation can be applied more generally to social networks defined by other relations than friendship: for instance, most people's sexual partners have had (on the average) a greater number of sexual partners than they have.

CentralNotice From Wikipedia, the free encyclopedia Jump to: navigation , search Potatoes The Potato Paradox is a mathematical calculation that has a counter-intuitive result. The "paradox" involves dehydrating potatoes by a seemingly minuscule amount, and then calculating a change in mass which is larger than expected. This is not to be confused for the Potato-Effect, which is sometimes known as the Potato Paradox, and is actually an economical paradox that was discovered in the potato-famine in Ireland in the 1840s. [ 1 ] 1 Description 2 Explanation 3 See also 4 References 5 External links Description [ edit ] The paradox has been described as: You have 100 lbs of Martian potatoes, which are 99 percent water by weight. You let them dehydrate until they're 98 percent water. How much do they weigh now? The Universal Book of Mathematics states the p...
