Sometimes when perusing the literature you come across an interesting algorithm, that while of dubious practical applicability, is none the less of novel interest. This post is about just such an algorithm. I can't be certain, but if i were to hazard a
It's no secret that when it comes to search structures, hash tables are fast. Performance wise, a hashtable can be much faster than any of the ordered search tree's frequently discussed in my posts. If your data doesn't require a
The relationship between binary search trees and linked lists is no secret. Without the use of some self balancing scheme any binary search tree has the potential to "devolve" into a linked list if subjected to a series of insertions in sorted order. I
Regular expressions and NFA have been an active area of study in theoretical computer science since the late 1950's. As such, there is a large body of work exploring a multitude of ways to evaluate regular expressions for the purpose of pattern matchin
Regular expressions are a fantastic way to describe patterns in text. Thanks to the work of pioneers like Stephen Kleene we know that for any regular expression there is cooresponding finite automaton (FA) and vice versa. This is known as Kleenes Theor
