HASCO is a framework for reducing configuration tasks (e.g. software system configuration or algorithm configuration) into an HTN planning problem. This can then in turn be reduced to a graph search problem that can be solved by any kind of standard graph search algorithm, e.g., breadth-first-search.

There is a newer version: 0.2.1
