| Abstract | Solution representation can have a large impact on the performance of heuristic solvers. When tackling bounded self-avoiding walk problems, such as the meander line RFID antenna design problem, solutions may be represented in terms of the absolute or relative direction of travel at each step. Encoding these instructions in a continuous space is required in order to apply continuous solvers, but also allows for an adaptive interpretation of each instruction that promotes longer paths. Using path length as a proxy for antenna quality, this work demonstrates that the adaptive solution representations outperform their non-adaptive counterparts, and that starting from a corner node in the square design space positively influences algorithm performance. The superior performance of a relative encoding over an absolute one is confirmed, in both the single objective of maximising path length and in a substantial investigation of the multi-objective antenna design problem. In the multi-objective case, simplifying the problem by fixing the antenna start node can assist the algorithm to perform well, but allowing the algorithm to evolve antennas starting from any point leads to more consistent results. |

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.
