When No One Web Service Works

A simple Example:

You know the circle diameter and need the radius. You have incomplete knowledge of the circle equations.

No web service operation takes Circumference as an input part name and has Radius as an output part name.

Consider the set of known functions: prove Yields( Radius, ?something)

Search for a web service that yields the same ?something from the Circumference.

That is, develop a plan for calling web services that has the effect of taking what is known and returning what is desired. Static process descriptions can't do this.
