| Abstract: |
| The computer algebra system CASS1 is designed by algebraic simplification method. In this survey, we only discuss some important algorithms for the CASSI, including rational expression canonical simplification algorithm, unnested radical expression canonical simplification algorithm and one species transcendental expression simplification algorithm. As an attempt at computer algebra system canonical construction, CASS1 was implemented by algorithm description language ALDES~[5]. |
