Algorithm is an important branch of mathematics, which involves many concepts and methods in mathematics. Graph theory, optimization theory, stochastic process, etc. Algorithms are widely used in computer science, artificial intelligence, finance and other fields. Some professors and researchers in the department of mathematics will also study the direction of algorithms, study the design, analysis and optimization of algorithms, explore the application of algorithms in different fields, or develop new algorithms to solve practical problems. Some professors and researchers in the department of mathematics may also cooperate with experts in computer science, artificial intelligence and other fields to carry out research on the direction of algorithms.
