Title of program: COMMUTE Catalogue Id: ACKS_v1_0 Nature of problem Commute is a Fortran program that can be used for the symbolic evaluation of equations of motion of operators or correlation functions. It can use symmetry operations to reduce the final number of terms and in some specific cases, it expresses correlation functions in terms of known functions. It is extremely useful for the calculation of the coefficients in the short-time expansion of a correlation function. Versions of this program held in the CPC repository in Mendeley Data ACKS_v1_0; COMMUTE; 10.1016/0010-4655(81)90034-5 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
