Talk:Reachability

Oracles?
In the "Algorithms" section:


 * "Typically algorithms for reachability that require preprocessing (and their corresponding data structures) are called oracles (similarly there are oracles for distance and approximate distance queries). "

The link to "oracles" needs to be reviewed. There are many Oracle pages in the disambiguation, but I believe that none of them match the usage invoked here. --Matt Westwood 07:00, 17 July 2010 (UTC)
