| Abstract | Concerns the development of a learning-based heuristic for scheduling heterogeneous machines. List scheduling methods are flexible enough to be used for a large class of problems, including the heterogeneous machine problem. However, designing a priority rule requires insight into the characteristics of the problem. We propose the iterative list scheduling, which refines priority rules while generating a number of schedules. We also show that the iterative list scheduling can be formulated as a reinforcement learning problem, defining states and actions. Due to the large number of possible states, reinforcement learning algorithms which use value functions in constructing an optimal policy may not be suitable for scheduling problems. Encoding the policies of reinforcement learning into genetic algorithms leads to the genetic reinforcement learning (GRL), which directly works with the policies rather than the values of states. A GRL-based scheduler, EVIS (Evolutionary Intracell Scheduler), has been applied to problems such as the heterogeneous machine scheduling, the job-shop scheduling, the flow-shop scheduling, and the open-shop scheduling problems. The proposed model of EVIS, which has the linear order of population-fitness convergence, was verified with computer experiments. Even without fine tuning of EVIS, the quality of solutions found by EVIS was comparable to that of problem-tailored heuristics for most of the problem instances. |

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.
