Simple Algorithm Sufficient for Many

but not All Web Service Composition Problems.

- Actions are web service calls.
- In addition to inputs and outputs, semantically annotate with descriptions of preconditions and effects.
- Regress back from a single goal condition.

Many web service composition problems in the literature can be done with this simple regression algorithm.
It is not planning and it is not in sufficient for all problems.
