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.

问题描述
COMMUTE是一款Fortran程序，可用于对算符的运动方程或关联函数进行符号求值。该程序可借助对称操作缩减最终项的数量，在部分特定场景下还能将关联函数以已知函数的形式表示。其在关联函数短时展开的系数计算中极具应用价值。
