| Abstract | With increasing numbers of features in automotive systems, feature interaction (FI) becomes more and more relevant regarding safety and emissions. Hence, undesired and potentially even unknown FIs pose a major challenge now to the automotive industry, but optimizing desired FI may even help to further reduce $CO_{2}$ emissions. We propose a new approach for optimization of feature interactions at run-time for automotive combustion engines. It integrates an optimization objective (minimize $CO_{2}$ emission) with both soft and hard constraints (e.g., related to certain temperatures). In the course of iterations of hill-climbing optimization at run-time, the integrating objective function is dynamically adapted for heuristic coordination of FIs. While our approach with its linear time and space complexity does not opt for finding globally optimal solutions, it coordinates feature interactions, both desired and undesired ones. Safety-critical problems are avoided using hard constraints and via release/inhibit conditions for features. Our prototypical implementation of this approach showed promising and realistic results in a simulation environment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
