Computer Algorithms: Data Compression with Prefix Encoding

Posted on February 6, 2012 by Stoimen

Overview Prefix encoding, sometimes called front encoding, is yet another algorithm that tries to remove duplicated data in order to reduce its size. Its principles are simple, however this algorithm tend to be difficult to implement. To understand why, first … Continue reading →

Computer Algorithms: Data Compression with Relative Encoding

Posted on January 30, 2012 by Stoimen

Overview Relative encoding is another data compression algorithm. While run-length encoding, bitmap encoding and diagram and pattern substitution were trying to reduce repeating data, with relative encoding the goal is a bit different. Indeed run-length encoding was searching for long … Continue reading →

JavaScript Performance: for vs. while

Posted on January 24, 2012 by Stoimen

JavaScript Loops If you have read some preformance tests on JavaScript loops, you may have heard that “while” is faster than “for”. However the question is how faster is “while”? Here are some results, but first let’s take a look … Continue reading →

Computer Algorithms: Data Compression with Diagram Encoding and Pattern Substitution

Posted on January 23, 2012 by Stoimen

Overview Two variants of run-length encoding are the diagram encoding and the pattern substitution algorithms. The diagram encoding is actually a very simple algorithm. Unlike run-length encoding, where the input stream must consists of many repeating elements, as “aaaaaaaa” for … Continue reading →
