The Department of Computer Science offers several A.B. and Sc.B. concentrations (a.k.a. majors) for undergraduates. The undergraduate program is designed to combine educational breadth in the areas of software, hardware, and theoretical computer science with deeper understanding of specialized areas such as software system design, programming languages, machine architecture, artificial intelligence, the analysis of algorithms, and the theory of computation. Computer science is now a critical tool for pursuing an ever-broadening range of topics, from outer space to the workings of the human mind. In most areas of science and in many liberal arts fields, cutting-edge work depends increasingly on computational approaches. The undergraduate program at Brown is designed to combine breadth in practical and theoretical computer science with depth in specialized areas. These areas range from traditional topics, such as analysis of algorithms, artificial intelligence, databases, distributed systems, graphics, mobile computing, networks, operating systems, programming languages, robotics and security, to novel areas including games and scientific visualization.
