Dear Maude Abusers, A new alpha release can be accessed at SRI-CSL in: ~eker/public_html/Maude/Alpha89f/ or downloaded from: http://www.csl.sri.com/~eker/Maude/Alpha89f/ Alpha release site authentication: User Name: maudeabuser Password: bughunter Bug fixes ---------- (1) Commutative unification which was broken by alpha89c now works gain. Provoked by this example from Santiago: fmod EXA is sort S . ops a b c : -> S [ctor] . op _+_ : S S -> S [comm ctor gather (e E)] . endfm unify a + b + c =? X:S . (2) A nasty bug reported by Santiago where the theory normalizer for ACU was converting the naive vector representation into red-black trees for sufficiently large argument lists when called from the AC unification algorithm which only understands the vector representation with resulting chaos. This is fixed by a quick hack of having a new function dumbNormalizeAtTop() which does no optimizations at all, even though some might be safe for unification. Steven
