T his page contains some informations about ACE release 3.0. Users already familiar with ACE may be interested in the differences between versions 2.0 and 3.0. New users of ACE may skip this part and proceed with the next pages. Many things have changed in ACE 3.0. In particular, names of functions have been normalized to be easily understood.
Available functions deal with comparisons, major indexes, conjugates, lists of compositions.
It is also possible to work in the plactic monoid, i.e. the free algebra of words modulo the plactic relations. It corresponds to an implementation of the Lambda-ring theory. Many function names have been changed, many functions have disappeared, either becoming internal functions or being included as options of other more general ones. Function names have been strictly normalized. New functions and algorithms have been included in already existing packages in order to improve their efficiency.
