Abstract RGIsearch is a C++ program that searches for invariants of a user-defined set of renormalization group equations. Based on the general shape of the β -functions of quantum field theories, RGIsearch searches for several types of invariants that require different methods. Additionally, it supports the computation of invariants up to two-loop level. A manual for the program is given, including the settings and set-up of the program, as well as a test case. Title of program: RGIsearch Catalogue Id: AEZQ_v1_0 Nature of problem The determination of renormalization group invariants, which can be used as a probe for the high-energy behaviour of theories in particle physics.
