This paper is an extended abstract of the recently published journal article (M. Goldenberg, The Heuristic Search Research Framework. Knowledge-Based Systems 129: 1–3. 2017). The Heuristic Search Research Framework is a software framework for implementing heuristic search algorithms and exploring their properties. The framework uses policy-based design to enable efficient, flexible and well-organized implementations. In addition, the framework provides effective tools for exploring the properties of the implemented algorithms. The extensive online documentation includes a video demo.
