1998-09-08 paulson 1998-09-08 Got rid of not_Says_to_self and most uses of ~= in definitions and theorems
1998-09-02 paulson 1998-09-02 small simplification to not_Says_to_self
1998-08-21 paulson 1998-08-21 Tidying
1998-07-31 paulson 1998-07-31 Removal of obsolete "open" commands from heads of .ML files
1998-07-02 paulson 1998-07-02 Deleted leading parameters thanks to new Goal command
1998-06-24 paulson 1998-06-24 Ran isatool fixgoal
1998-03-07 nipkow 1998-03-07 Removed `addsplits [expand_if]'
1998-01-12 paulson 1998-01-12 Tidying, mostly to do with handling a more specific version of Fake_parts_insert
1997-12-24 paulson 1997-12-24 New Auto_tac (by Oheimb), and new syntax (without parens), and expandshort
1997-12-23 paulson 1997-12-23 Tidied using more default rules
1997-12-19 wenzelm 1997-12-19 tuned;
1997-12-16 paulson 1997-12-16 Simplified proofs using rewrites for f``A where f is injective
1997-11-11 paulson 1997-11-11 Made some proofs more robust
1997-11-03 wenzelm 1997-11-03 isatool fixclasimp;
1997-10-17 nipkow 1997-10-17 setloop split_tac -> addsplits
1997-09-25 paulson 1997-09-25 Tidied proofs, using Clarify_tac
1997-09-18 paulson 1997-09-18 Global change: lost->bad and sees Spy->spies First change just gives a more sensible name. Second change eliminates the agent parameter of "sees" to simplify definitions and theorems
1997-09-16 paulson 1997-09-16 Deleted the redundant simprule not_parts_not_analz
1997-07-14 paulson 1997-07-14 Changing "lost" from a parameter of protocol definitions to a constant. Advantages: no "lost" argument everywhere; fewer Vars in subgoals; less need for specially instantiated rules Disadvantage: can no longer prove "Agent_not_see_encrypted_key", but this theorem was never used, and its original proof was also broken the introduction of the "Notes" constructor.
1997-07-11 paulson 1997-07-11 Removal of monotonicity reasoning involving "lost" and the theorem Agent_not_see_encrypted_key, which (a) is never used and (b) becomes harder to prove when Notes is available.
1997-06-27 paulson 1997-06-27 Corrected indentations and margins after the renaming of "set_of_list"
1997-06-26 nipkow 1997-06-26 set_of_list -> set
1997-05-07 paulson 1997-05-07 Conversion to use blast_tac (with other improvements)
1997-02-15 oheimb 1997-02-15 reflecting my recent changes of the simplifier and classical reasoner
1997-01-23 paulson 1997-01-23 Tidied proofs by using "etac rev_mp" instead of applying rev_mp to result()
1997-01-17 paulson 1997-01-17 Now with Andy Gordon's treatment of freshness to replace newN/K
1997-01-09 paulson 1997-01-09 New treatment of nonce creation
1997-01-07 paulson 1997-01-07 Tidied up the unicity proofs
1996-12-19 paulson 1996-12-19 Extensive tidying and simplification, largely stemming from changing newN and newK to take an integer argument
1996-12-16 paulson 1996-12-16 New tactics: prove_unique_tac and analz_induct_tac
1996-12-13 paulson 1996-12-13 Streamlined many proofs
1996-12-05 paulson 1996-12-05 Minor speedups
