2007-06-13, by huffman
reactivated theory Class;
2007-06-13, by wenzelm
added the Q_Unit rule (was missing) and adjusted the proof accordingly
2007-06-13, by urbanc
* Isar: method "assumption" (implicit closing of subproofs) takes non-atomic goal assumptions into account;
2007-06-13, by wenzelm
generate_fresh works even if there is no free variable in the goal
2007-06-13, by narboux
tuned;
2007-06-13, by wenzelm
tuned proofs: avoid implicit prems;
2007-06-13, by wenzelm
removed constant int :: nat => int;

thm antiquotations
2007-06-13, by huffman
transaction: context_position (non-destructive only);
2007-06-13, by wenzelm
added map_current;
2007-06-13, by wenzelm
tuned msg;
2007-06-13, by wenzelm

2007-06-13, by wenzelm
renamed map to map_current;
2007-06-13, by wenzelm

2007-06-13, by wenzelm
removed unused is_atomic;
2007-06-13, by wenzelm

2007-06-13, by wenzelm
merge/merge_refs: plain error instead of exception TERM;
2007-06-13, by wenzelm
Context positions.
2007-06-13, by wenzelm
added context_position.ML;
2007-06-13, by wenzelm

thm antiquotations
2007-06-12, by huffman
add lemma inj_of_nat
2007-06-12, by huffman
thm antiquotations
2007-06-12, by huffman
Unfortunately needed patch due to incompatibility with SML -- oo is infix and hence can not appear on the left handside of patterns
2007-06-12, by chaieb
changed int stuff into integer for SMLNJ compatibility
2007-06-12, by chaieb
more of_rat lemmas
2007-06-12, by huffman
add function of_rat and related lemmas
2007-06-12, by huffman
turned curry (op opr) into curry op opr --- because of smlnj
2007-06-12, by chaieb
De-overloaded operations for int and real.
2007-06-12, by wenzelm
SML basis with type int representing proper integers, not machine words.
2007-06-12, by wenzelm
Tuned proofs : now use 'algebra ad: ...'
2007-06-12, by chaieb
cooper_tac takes now two lists of theorems to be added/deleted from the simpset dor pre-simplification
2007-06-12, by chaieb
changed val restriction to local due to smlnj
2007-06-12, by chaieb
Changed normalizer Data to contain a simpset besides the list of instances; Before the method starts, it simplifies with this simpset; Added attribute 'algebra' to add and delete theorems from the simpset above;
2007-06-12, by chaieb
Added algebra_tac; tuned;
2007-06-12, by chaieb
Method now takes theorems to be added or deleted from a simpset for simplificatio before the core method starts
2007-06-12, by chaieb
algebra_tac moved to file Tools/Groebner_Basis/groebner.ML; Method now takes theorems to be added or deleted from a simpset for simplificatio *before* the core method starts
2007-06-12, by chaieb
nex example
2007-06-11, by nipkow
Conversion for computation on constants now depends on the context
2007-06-11, by chaieb

2007-06-11, by chaieb
Added dependency on file Groebner_Basis.thy
2007-06-11, by chaieb
Added instantiation of algebra method to fields
2007-06-11, by chaieb
hid constant "dom"
2007-06-11, by nipkow
Removed from CVS, since obselete in the new Presburger Method;
2007-06-11, by chaieb
Generated reflected QE procedure for Presburger Arithmetic-- Cooper's Algorithm -- see HOL/ex/Reflected_Presburger.thy
2007-06-11, by chaieb
Added more examples
2007-06-11, by chaieb

2007-06-11, by chaieb
tuned
2007-06-11, by chaieb

2007-06-11, by chaieb
tuned tactic
2007-06-11, by chaieb
Temporarily use int instead of IntInf.int but Code generator should map HOL's int to ML's IntInf.int --- To be fixed
2007-06-11, by chaieb
tuned Proof and Document
2007-06-11, by chaieb
tuned Proof
