Cześć :) Na początku chciałam się przywitać, jestem tu nowa.
Mam prośbę, znalazłby się ktoś, kto sprawdziłby mi streszczenie artykułu, które napisałam? Jest w nim pewnie wiele błędów, więc równocześnie prosiłabym o korektę.
Z góry dziękuję za pomoc :)
Algorithms – Business by numbers
This article from “The Economist” is about algorithms in business. It can be said that the algorithms constitute the basic of many aspects of our life and it bounds to take over the world. Algorithm is a step-by-step procedure for calculations. In mathematics and computer science, an algorithm usually means a procedure that solves a recurrent problem.
Many conditions must be achieved that algorithms will work properly. The system within algorithms run must be intuitive. The inputs must have to be right. Otherwise, the algorithm will apply correctly, but the resulting data will be wrong or absurd.
People deal with the performance of simple calculations however; they often make mistakes when it comes to tasks that are more complicated. This is quite different from the computers that based on various algorithms can solve problems that people can’t.
These problems typically fall into two types:
• Improving various;
• Analysing data;
An example of first types is algorithm called VOLCANO. UPS use VOLCANO to solve “travelling – salesman problem”. Given a list of cities and their pair wise distances, the task is to find the shortest possible route that visits each city exactly once and returns to the origin city. A VOLCANO is planning scheduling, facilitation and maximise efficiency. In that UPS has saved tens of millions of dollars since its introduction in 2000.
An example of second types is “the rolling ball algorithm”. Analysts from the Dunnhumby Company created it to assign attributes to each of the products on Tesco’s shelves. When every product is categorised, Dunnhumby is able to segment and accrue Tesco’s customers based on what they bought. This is helpful in determination, which products should be in the shop side by side. Digital media will help to see what people read online or watch on TV and how it impact on what they are buying in the shop.
Algorithms are also often associated with search engines. In fact, if you browse for a book, movie on DVD or something like that, algorithms generate recommendation for other titles to buy. The merchants knowing, what you want to buy, show you a products, which other people also bought. Companies are collecting details about customers, because they want to respond to each customer in a personalised way.
