00616e45ed - Bit masking was incorrect: & binds less strong than == ! 
This caused many of the --experimental switches not to work.

cf832ca1b1 - Seems to work again, but further testing is needed. 2006-02-27 22:27:09 +00:00

b49d13b6ee - [[[ Broken commit. ]]] 
Stuff seems to be working again, slightly less efficient though (count
  states).

Committing partial new Warshall work because it is getting too big.

1d3d154a2f - If the timebound is hit, it should be reported anyway, because the 
results are not to be trusted anymore.

b16023bf0e - Cleaned up heuristic code. Note that there is a "hidden" heuristic: 
implicitly, older goals are resolved first, if some goals have equal
  weights. This is encoded in the "w <=" comparison; if this is set to
  "w <", the heuristic becomes much less effective.

f376260512 - Changed default heuristic to 34. 2006-02-22 15:57:55 +00:00
ccremers
41e797413c - Added new heuristics based on hidelevel results. 
Preliminary results:
  1. For typed matching, either heuristic 32 or 34 are best, and far
  superior to the previous best (3).
  2. For untyped matching, partial tests indicate that heuristic 1 is
  best, which is rather interesting.

921c82876d - experimental=4 now disables some things. Weirdly enough, they don't 
seem to make much difference.

first. Revealed by the certified e-mail protocol by Abadi and
  Blanchet.

6f670d7ab6 - In xml output, renamed 'attack' tag to 'state', which in general 
reflects better what it describes.

ccremers
c79c9eb73f - Added color output but forgot to add the sources files, fixed. 
- Note: ~ is not expanded in SCYTHERDIR because it is not handled by the
  shell; thus $HOME should be used.
 2005-12-29 11:03:18 +00:00

39adf85c6a - Reverted previous version: Tickets can possibly be secret as well 
(although this is dubious, as the claiming role will not know the
  contents in many cases)
 2005-12-28 12:04:00 +00:00

cb2aef3915 - Old state/time info has now been removed. This was only needed for the 
POR engine anyway, so that's where it is shown now.

32f226f782 - Better switches explanation. 2005-12-22 12:33:35 +00:00

Alice.

5276630007 - FIX: DOS newlines are now also accepted. 2005-11-28 08:27:05 +00:00
ccremers
e51b54af23 - FIX: Instantiation of variables is now the default. 
- NEW: -C --class switch to reset this.
- NEW: max runs is now 6 by default for usability. For unbounded search,
  use -r 0 or --maxruns=0
 2005-11-12 21:26:50 +00:00

41132afea3 - Finally fixed the 'IV', 'RV' nuissance for global variables such as 
the role names.
 2005-11-12 21:16:02 +00:00

c1c0b856de CHG: Changed default behaviour to Arachne engine. 
NEW: Added 'S' switch for --summary things.
 2005-11-04 13:23:30 +00:00
ccremers
5e1ca56f87 - Added experimental feature: explicit unique origination. This has to 
be investigated further, because it seems to reduce just a few states.
  Note to Gijs: stay away from this, you should be writing your thesis.

9f8f04c41c - Switched to the new consistency checking base. 2005-10-08 20:47:31 +00:00

included more comments.

ccremers
2452a34671 - Added 'termlistMinusTermlist' function. 
- Added TERMLISTERROR constant, and corresponding tests.
  Note that this will not work in many contexts, because only NULL is
  usually considered to be a special value. It is purely intended for
  the new type evaluation functions in type.c.
 2005-10-08 19:56:04 +00:00

fe730716ca - Added 'agenttypecheck' switch. 2005-10-08 19:54:30 +00:00
ccremers
a3b009f119 - The state of sys->variables was not maintained correctly, because 
terms were destroyed before it could be tested whether they were in
  sys->variables. Thus, garbage was left in sys->variables. This has
  gone undetected because it was never really used. Hmpf.
 2005-10-08 19:53:10 +00:00

ea5bc6893f - Slightly smarter substitution in the symmetric case, when we make Var1 
equivalent to Var2.
 2005-10-07 20:38:41 +00:00

5b73d707a0 - Rewrite of actor/agent type consitency code: now more aware of 
initiator/responder difference.

5c0c5d3333 - Better XML output for variables section. 2005-09-08 13:30:00 +00:00
ccremers
01a45f87d2 - Rewrote variables section, integrated typeflaw info. 
Note that for variables that are not instantiated, only the variable
  and the type info is shown. For instantiated variables, both are
  shown.
  In this output the attribute 'free' should be ignored, as its
  output is not accurate here.
 2005-09-08 12:55:32 +00:00
ccremers
48574de13e - Minor improvement to type flaw output: now also shows the type of the 
substituted term.
 2005-09-07 07:21:13 +00:00
ccremers
e104dddbfb - Added a switch to number the limit of intruder actions. 
Initial testing suggests it does not influence the number of states
  much for values of 2 and higher.
 2005-08-21 21:38:32 +00:00

c330a5b719 - Added some thoughts. 2005-08-21 21:36:00 +00:00
