A composite number is a number that has more divisors then just 1 and itself. For example the number 6 has 4 divisors, namely: 1, 2, 3, and 6. We call these factors of the number 6. The first 10 composite numbers greater than 1 are: 4, 6, 8, 9, 10, 12, 14, 15, 16, and 18.
International Conference on Intelligent Robots and Systems (IROS) The IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) is one of the largest and most impacting robotics research conferences worldwide. Established in 1988 and held annually, IROS provides an international forum for the international robotics research community to explore the frontier of science and technology in intelligent robots and smart machines.
Information retrieval (IR) is the activity of obtaining information resources relevant to an information need from a collection of information resources. Searches can be based on full-text or other content-based indexing. Information retrieval is the science of searching for information in a document, searching for document themselves, searching for metadata that describe data and for databases such as text, image or sound. Automated information retrieval systems are used to reduce what has been called information overload.
