All systems in modern information and communication technology are built on algorithms. The Center focuses on the algorithmic challenges in applied computer science viz. the design of advanced IT systems. We aim at highly effective algorithmic solutions that exploit structure in information and efficient computation in any context.

The Center for Algorithmic Systems is headed by professor Jan van Leeuwen, is part of the Department of Information and Computing Sciences of Utrecht University, and a member of the inter-university research school IPA.

`Algorithmic Systems'

The term `Algorithmic Systems' was used for the first time in the First ACM Turing Award Lecture, by Alan J. Perlis in 1966: The Synthesis of Algorithmic Systems, see J.ACM 14 (1967) 1-9.
