GP (for Graph Programs) is a rule-based, nondeterministic programming language for solving graph problems at a high level of abstraction, freeing programmers from handling low-level data structures. The core of GP consists of four constructs: single-step application of a set of conditional graph-transformation rules, sequential composition, branching and iteration. The language has a structural operational semantics, as well as a prototype implementation.

Sandra Steinert, Greg Manning, and Detlef Plump worked on the design and implementation of GP; Chris Poskitt and Detlef Plump are currently investigating the formal verification of Graph Programs.
