This paper considers the problem of evolving machines that accept specific patterns within a sequence of' events (c.g. for event correlation). A set of fundalnental relation ships (spatial and temporal) among events is identified, and a compact and descriptive notation for specifying correla tion patterns is derived. This notation is then clapped to a tree structure amenable to genetic programming operators, which allows evolution of correlation patterns. This work is partially funded by the EC 6th Frame work IST project Misuse I'.letection System (1ST-026459).

This paper considers the problem of evolving machines that accept specific patterns within a sequence of events (e.g. for event correlation). A set of fundamental relationships (spatial and temporal) among events is identified, and a compact and descriptive notation for specifying correlation patterns is derived. This notation is then mapped to a tree structure amenable to genetic programming operators, which allows evolution of correlation patterns.
