This book presents the collection of the accepted research papers presented in the 1st 'International Conference on Computational Intelligence and Sustainable Technologies (ICoCIST-2021)'. This edited book contains the articles related to the themes on artificial intelligence in machine learning, big data analysis, soft computing techniques, pattern recognitions, sustainable infrastructural development, sustainable grid computing and innovative technology for societal development, renewable energy, and innovations in Internet of Things (IoT).

The book constitutes proceedings of the 12th Industry Symposium held in conjunction with the 18th edition of the International Conference on Distributed Computing and Intelligent Technology (ICDCIT 2022). The focus of the industry symposium is on Mobile Application Development: Practice and Experience. This book focuses on software engineering research and practice supporting any aspects of mobile application development. The book discusses findings in the areas of mobile application analysis, models for generating these applications, testing, debugging & repair, localization & globalization, app review analytics, app store mining, app beyond smartphones and tablets, app deployment, maintenance, and reliability of apps, industrial case studies of automated software engineering for mobile apps, etc. Papers included in the book describe new or improved ways to handle these aspects or address them in a more unified manner, discussing benefits, limitations, and costs of provided solutions. The volume will be useful for master, research students as well as industry professionals.

The study has touched upon a number of theoretical and empirical issues relating to the formulation of strategy for the development of a Himalayan- destination. Three broad issues of the book are destination marketing, perception and attitudes of local people for tourism in Sikkim and resource analysis for tourism with all available natural and socio-cultural resources. The present study dealt with all these issues in the backdrop of the controversy between conventional institutionalized development of tourism in the Himalayan State Sikkim and it's mostly needed sustainable development orientation therein. The main chapters we have dealt with are Analysis of Tourism Environment to Categorize the Significant Events and Trends, resource analysis for the Destination, development of an effective marketing mix to enable the State to Maximize Its Tourism Potentialities, roles and responsibilities Played by the State Government, understanding of perception and attitudes in tourism with an empirical assessment of opinion of the local people and public representatives, and destination marketing.
