Cellular automaton (CA) is a paradigm of unconventional fine-grained parallel computation that is being extensively used to model several applications in real life. Introduced in 2021 on the platform of Cellular Automata India, this school offers a state-of-the art research based interdisciplinary internship program on cellular automata (CAs) for the undergraduate students. Here, an introductory course on CAs is offered and then some research projects are given to the students to choose. Each student has to work on a project which will be mentored by expert(s) on that field and submit a project report. Certificate will be issued based on their performance in the final examination including a written test and a presentation on project.
