Before revision:  As a non-chemical application we use the framework of exploration strategies to model an abstract graph rewriting problem to construct high-level transformations that cannot be directly represented by the Double-Pushout formalism starting from simple DPO transformation rules .
After revision:  As a non-chemical application we use the framework of exploration strategies to model an abstract graph rewriting problem to construct high-level strategy framework. The ideas presented here can not only be used for a strategy-based chemical space exploration that has close correspondence of experimental results, but are much more general. In particular, the framework can be used to emulate higher-level transformation models such as illustrated in a small puzzle game .
