A collection of miscellaneous algorithms.

Sorts the nodes of an acyclic graph so that if node X points to node Y then Y appears before X in the list. Read more.
Basically, it's useful for resolving a dependency graph.
// A description of a graph: $edges = array( 'B' => array('C', 'D'), // Node B points to nodes C and D 'A' => array('B'), // Node A points to node B 'C' => array('D'), // Node C points to node D ); $nodesSorted = \Xi\Algorithm\TopologicalSort::apply($edges); // $nodesSorted is now array('D', 'C', 'B', 'A')
Running the tests
No dependencies to other libraries exist, but in order to generate an autoloader first run
composer.phar install --dev
and then run the tests with
phpunit -c tests
