imitator-model-checker/imitator

release 2.7 (2015-07-22)

Major algorithmic features since 2.6.1

Added EF-synthesis (option "-mode EF"): synthesize all parameter valuations such that a given state is reachable [AHV93,JLR15]
Added PRP and PRPC algorithms (option "-PRP") [ALNS15]
Added a distributed version of the behavioral cartography (option "-distributed"), with several distribution schemes:
- static [ACN15]
- sequential [ACE14]
- random [ACE14]
- shuffle [ACN15]
- dynamic [ACN15]
- unsupervised / unsupervised multi-threaded (unpublished, EXPERIMENTAL)

Syntax improvement

Options

Add two new verbose modes: mute and warning-only
Add export to LaTeX/TikZ
The result (text) can be exported to a file (option "-output-result")
Time elapsing can be applied either at the beginning (new mode, option -no-time-elapsing) or at the end (classical IMITATOR semantics) of the computation of a new state
New options to specify min/max values for x/y axes for the graphical output of the cartography
Removed -counterex option (stops the analysis as soon as a counterexample is found)

Changes in options syntax

mode "reachability" becomes mode "statespace"
"-cart" becomes "-output-cart"
"-fancy" becomes true by default; to disable it, use "-output-trace-set-nodetails"
"-log-prefix" becomes "-output-prefix"
"-with-dot" becomes "-output-trace-set"
"-with-graphics-source" becomes "-output-graphics-source"
"-with-log" becomes "-output-states"
"-with-parametric-log" is removed (becomes always true when option "-output-states" is enabled)

Interfacing with CosyVerif (and GrML support)

Add EF mode support to the CosyVerif interface (using options -fromGrML and -cosyProp)
Fix a bug in the GrML output (action labels were removed when exporting to GrML)
Add the initial constraint to both the GrML input and the GrML output

Misc

Add suffix "-pta.jpg" to PTA2JPG files
In BC mode: try to reduce the number of constraint (inclusion test in both directions)
Warning displayed if parameters are not constrained to be >= 0 in the model
Improve printing floating numbers (in time and memory statistics)

Versioning

Now IMITATOR has a build number (since May 2013)
Now IMITATOR has a version name and a version logo (based on traditional Breton "galettes" ingredients): 2.7 is "Butter Guéméné"

Install and compile

Main binary now in lower case ("imitator")
Two versions:
- non-distributed (sh compile.sh), that creates a static binary "imitator", or
- distributed (sh compile-distr.sh), that creates a dynamic binary "patator"
