Adaptive Programming (AP) provides a graph-based model for separating the traversal of a data structure from computations over the structure. This paper presents a new programming paradigm in AP that adds the power of functional composition of VISITOR methods while preserving the flexibility of traversal control. The paper departs from a pure iterative approach to AP and introduces a recursive approach using default combination methods to achieve adaptiveness. Default combination methods are a novel form of advice that adapts to the number of outgoing edges the traversal joinpoint uses.
