Abstract Graph Algorithms
David Gibson <[email protected]>
This modules contains several standard graph algorithms, implemented so that they don't rely on a specific representation of the graph structure. Instead, user supplied callbacks can compute the graph's edges as required. Graph nodes can even be constructed on the fly as they're discovered by edge traversal.
The algorithms do require a certain amount of persistent data per-node. The module doesn't allocate, so the callbacks are required to include an aga_node field inside new nodes when they're discovered. Because this relies on a structure embedded within the caller's representation of the graph nodes/states, it's not re-entrant - only one aga algorithm can be running at a time (per aga_node instance).
