New Conf. Paper: ICPP 2013

The paper: Protein Structure Prediction on GPU:  a Declarative Approach in a Multi-agent Framework, by F. Campeotto, A. Dovier, and E. Pontelli is accepted in ICPP conference (IEEE) Lyon (FR), October 2013.


This paper provides a novel perspective in  the Protein Structure Prediction (PSP) problem. The PSP problem focuses on determining putative 3D structures of a protein starting from its primary sequence. The proposed approach relies on a multi-agents approach, where concurrent agents explore the folding of different parts of a protein. The strength of the approach lies in the agents’ ability to apply different types of knowledge (expressed in the form of  declarative constraints to prune the local space of folding alternatives. The paper demonstrates the suitability of a GPU approach to  implement such multi-agent infrastructure, with significant improvements in speed and quality of solutions w.r.t. other methods (e.g., based on  fragments assembly approaches).
