Computational Intelligence (CI) is revolutionizing the technology enabled solutions in almost every domain. Amalgamation of Artificial Intelligence(AI) with evolving computational technologies has been realized as a fast growing new approach from research and development to various domains like healthcare, business, education, travel, gaming and entertainment to provide self-sustainable advanced information processing and applications. To create and automate the flexible information processing and services with humans like abilities such as sensing, understanding, learning, recognizing and thinking, CI playing a vital role. For better analyzing the social and global challenges and improving the computational performance across the domain, Intelligent and sustainable engineering solutions needs continuous innovations, research and development. The aim of this second IEEE-International Conference on Computational Intelligence and Sustainable Engineering (CISES-2023) to provide an opportunity to the global community researchers, scientists, research scholars, solution developers, practitioners and budding professional on amalgamation of sustainable engineering solutions development and computational intelligence innovations. The key attempt of CISES-2023 is to bring together the global participants for exploring and sharing an intact idea not only to bridge the research gaps, but also to establish international research collaborations in their career path. Hopefully, the outcome must boost the participants towards the theme of the conference and encourage them for their significant contributions in sharing their scientific knowledge, during the subsequent series of the conferences as well.
