| Abstract | Summary form only given. Constraint optimization exists in many natural-computation applications, including neural and evolutionary computations. A key observation on the constraints of many of these application problems is that they are highly structured and involve variables with strong spatial or temporal locality. Based on this observation, large-scale problems in these applications can be partitioned by their constraints into a small number of much simpler subproblems. Because each subproblem has only a fraction of the original constraints, it is a significant relaxation of the original problem and has a dramatically lower complexity. As a result, many problems that cannot be solved before can now be solved easily. In this talk, we present the application of this approach in solving nonlinear optimization and automated planning problems. Based on a partition-and-resolve strategy, we evaluate penalty-based techniques for resolving violated global constraints. We further examine the limitations on using penalties to guide the evaluation of the partitioned constraints in planning problems. We argue that a top-down state-space approach is better and demonstrate its effectiveness on nonlinear constrained optimization and automated planning benchmarks. |

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.
