| Abstract | Ant Colony Optimization Algorithms are the most successful and widely accepted algorithmic techniques based on the decentralized collaborative behavior of real ants when foraging for food. The initialization of pheromone in these algorithms is an important step because it dictates the speed of the system's convergence to the optimal solution. All the proposed initialization techniques in the literature use a single value to initialize the pheromone on all edges. In our paper, instead of using a constant or a pre-calculated value to initialize the pheromone the edges, we propose a local pheromone initialization technique that involves the ants initializing the edges, using local information, as they encounter the edges for the first time. We tested our proposed local initialization using the Ant Colony System algorithm to solve the Travelling Salesman Problem. Our approach, when compared to the standard initialization approaches, provided better results in more than 70% of the tested datasets. Also, our algorithm did not require an initialization for all edges. In general, our local pheromone initialization approach was successful in achieving a balance between the solution quality and the time required to construct that solution even in the cases in which it was not able to find the optimal path. |

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.
