Algorithm


In science and technology an algorithm is a procedure to solve a mathematical problem with calculations and data processing. With current computers algorithms can be run automatically: the individual steps of the algorithm are encoded as instructions in a program and afterwards the program is executed.


Search engines use algorithms as well to sort their indexed websites by relevance to the searched term. Depending on its profile, each search engine has its own algorithm.

Google for instance uses its own algorithm to calculate the PageRank. The PageRank plays an important role in a website's search results position.
