| Abstract | The Traveling Salesman Problem (TSP) has been used to model many real world applications. In this problem, a salesman travels using the shortest route between the cities that he must visit and returns to the depot. If it is required to use more than one salesman in the solution, the problem is called multiple Traveling Salesman Problem (mTSP), and the objective is to minimize the overall distance traveled by them. However, when only the overall distance is minimized, depending on the distribution of the cities, some salesmen tend to travel much more than others. This paper presents the development of Genetic Algorithms (GAs) to reduce both the overall distance and the difference between the distance traveled by each salesman. Since there are more than one objective to be optimized, two approaches were evaluated. A multi-objective GA and a mono-objective GA with a fitness function that combines both objectives. In order to find the best results for each approach, different methods for crossover and selection have been used. Experimental results show the effectiveness of the proposed GAs. The results further indicate that, considering both objectives, the multi-objective GA generates more balanced solutions for almost all 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.
