pbesinst
Usage
pbesinst [OPTION]... [INFILE [OUTFILE]]
Description
- Transforms the PBES from INFILE into an equivalent BES and writes it to OUTFILE. If INFILE is not present, standard input is used. If OUTFILE is not present, standard output is used.The format of OUTFILE is determined by its extension (unless it is specified by an option). The supported formats are:
‘pbes’ for the mCRL2 PBES format, ‘bes’ for the mCRL2 BES format,
Command line options
-iFORMAT , --in=FORMAT
use input format FORMAT:
pbesPBES in internal format
pgsolverBES in PGSolver format
textPBES in textual (mCRL2) format
-oFORMAT , --out=FORMAT
use output format FORMAT:
besBES in internal format
pbesPBES in internal format
pgsolverBES in PGSolver format
textPBES in textual (mCRL2) format
-QNUM , --qlimit=NUM
limit enumeration of universal and existential quantifiers in data expressions to NUM iterations (default NUM=10, NUM=0 for unlimited).
-e , --remove-equations
remove redundant equations
-rNAME , --rewriter=NAME
use rewrite strategy NAME:
jittyjitty rewriting
jittyccompiled jitty rewriting
jittypjitty rewriting with prover
-zNAME , --search=NAME
search the state space using strategy NAME:
breadth-firstCompute the right hand side of the boolean variables in a first come first served basis. This is comparable with a breadth-first search. This is good for generating counter examples.
depth-firstCompute the right hand side of a boolean variables where the last generated variable is investigated first. This corresponds to a depth-first search. This can substantially outperform breadth-first search when the validity of a formula is determined at a larger depth.
bShorthand for breadth-first.
dShorthand for depth-first.
-f[PARAMS] , --select[=PARAMS]
select finite parameters that need to be expanded. Examples: –select=X1(b:Bool,c:Bool);X2(b:Bool) or –select=*(*:Bool). Note: this option only has effect when used together with –strategy=finite.
-sNAME , --strategy=NAME
compute the BES using strategy NAME:
lazyfor computing only boolean equations which can be reached from the initial state
alternative-lazyan alternative version of the lazy strategy that supports more options
finitefor computing all possible boolean equations
--timings[=FILE]
append timing measurements to FILE. Measurements are written to standard error if no FILE is provided
-ONAME , --transformation=NAME
optimize the BES using strategy NAME:
0Compute all boolean equations which can be reached from the initial state, without optimization. This is is the most data efficient option per generated equation.
1Optimize by immediately substituting the right hand sides for already investigated variables that are true or false when generating an expression. This is as memory efficient as 0.
2In addition to 1, also substitute variables that are true or false into an already generated right hand side. This can mean that certain variables become unreachable (e.g. X0 in X0 and X1, when X1 becomes false, assuming X0 does not occur elsewhere. It will be maintained which variables have become unreachable as these do not have to be investigated. Depending on the PBES, this can reduce the size of the generated BES substantially but requires a larger memory footprint.
3In addition to 2, investigate for generated variables whether they occur on a loop, such that they can be set to true or false, depending on the fixed point symbol. This can increase the time needed to generate an equation substantially.
