| Abstract | In this paper, we propose a new method for solving the reinforcement learning problem in a dynamically changing environment, as in vehicle navigation, in which the Markov decision process used in traditional reinforcement learning is modified so that the response of the environment is taken into consideration for determining the agent's next state. This is achieved by changing the action-value function to handle three parameters at a time, namely, the current state, action taken by the agent, and action taken by the environment. As it considers the actions by the agent and environment, it is termed "double action". Based on the Q-learning method, the proposed method is implemented and the update rule is modified to handle all of the three parameters. Preliminary results show that the proposed method has the sum of rewards (negative) 89.5% less than that of the traditional method. Apart from that, our new method also has the total number of collisions and mean steps used in one episode 89.5% and 15.5% lower than that of the traditional method respectively. |

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.
