title = {Reasoning in complex environments with the SelectScript declarative language}, author = {Andr\’e Dietrich and Sebastian Zug and Luigi Nardi and J\”org Kaiser}, url = {http://arxiv.org/abs/1508.04159 http://nbviewer.ipython.org/url/gitlab.com/OvGU-ESS/SelectScript_demos/raw/master/DSLRob-15/presentation.ipynb}, SelectScript is an extendable, adaptable, and declarative domain-specific language aimed at information retrieval from simulation environments and robotic world models in an SQL-like manner. In this work we have extended the language in two directions. First, we have implemented hierarchical queries; second, we improve efficiency enabling manual design space exploration on different "search" strategies. We demonstrate the applicability of such extensions in two application problems; the basic language concepts are explained by solving the classical problem of the Towers of Hanoi and then a common path planning problem in a complex 3D environment is implemented.
