Recursion is when the "solution to a problem depends on solutions to smaller instances of the same problem" (wiki). Inception? Haha There are different types of recursion: 1. Single Recursion - only contains a single self-reference ex. list traversal (linear search), computing the factorial function 2. Multiple Recursion - contains multiple self-references ex. tree traversal (depth-first search), computing the Fibonacci sequence 3. Indirect Recursion - when a method invokes another method, eventually resulting in the original method being invoked again 4. Anonymous recursion - does not explicitly call a function by name Recursion is important in artificial intelligence because it involves searching through nested structures. Anything involving tree data structures will require some recursion. wiki source: http://en.wikipedia.org/wiki/Recursion_(computer_science)
Recursion is one of the most confusing things to me XD
@TechAtHeart you are not alone my friend :P
