| Abstract | Finding optimal inputs for a multiple input, single output system is taxing for an system operator. This work presents a population-based optimization to create sets of functions to approximate a locally optimal input as an operator selects an output. Output and cost functions are modeled by neural networks. Neural network gradients are used to optimize a population of agents by minimizing the cost for the agent's current output. When an agent reaches an optimal input for its current output, additional agents are generated to step in the output gradient directions. The agent then settles to the local optimum for the new output value. The set of associated optimal points forms a inverse function, via spline interpolation, from a desired output to an optimal input. In this manner, a locally optimal function is created for each settled agent. These functions are naturally clustered in input and output spaces allowing for a continuous optimal function. The best cluster over the anticipated range of desired outputs can be chosen and the process optimized on-the-fly to respond to different set points. Results are shown for a diverse set of functions. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
