filter promotion (algorithm) In a generate and test algorithm, combining part of the filter with the generator in order to reduce the number of potential solutions generated. A trivial example:
filter (< 100) [1..1000] ==> [1..99]
where [1..n] generates the list of integers from 1 to n. Here the filter has been combined completely with the generator. This is an example of fusion. Last updated: 2005-03-18
