Providing Concise Database Covers Instantly by Recursive Tile Sampling [chapter]

Sandy Moens, Mario Boley, Bart Goethals
2014 Lecture Notes in Computer Science  
It is based on the recursive application of a simple tile sample procedure that can be implemented e ciently using rejection sampling.  ...  one of two key requirements: a) to provide results within a short response time of only a few seconds and b) to return a concise set of patterns with only a few elements that nevertheless covers a large  ...  We therefore remove these cells from the conditional database. Pseudo code for Recursive Tile Sampling, RTS, is given in Algorithm 1.  ...
