Abstract
In [1], we introduced Planning by Rewriting (PBR),
a new paradigm for efficient high­quality planning that
exploits plan rewriting rules and efficient local search
techniques to transform an easy­to­generate, but possi­
bly suboptimal, initial plan into a low­cost plan. In this
paper we show in detail the application of the general
framework to query planning in distributed environ­
ments. As a result we obtain an scalable and flexible
query planner for use in an information mediator.
