PROGRAM:

NAME

pbes2bes - Generate a BES from a PBES.

SYNOPSIS

pbes2bes [OPTION]... [INFILE [OUTFILE]]

DESCRIPTION

Reads the PBES from INFILE and writes an equivalent BES to OUTFILE. If INFILE is not
present, stdin is used. If OUTFILE is not present, stdout is used.

OPTIONS

OPTION can be any of the following:

-eLEVEL, --erase=LEVEL
use remove level LEVEL to remove bes variables 'none' do not remove generated bes
variables. This can lead to excessive usage of memory. (default) 'some' remove
generated bes variables that are not used, except if the right hand side of its
equation is true or false. The rhss of variables must have to be recalculated, if
encountered again, which is quite normal. 'all' remove every bes variable that is
not used anymore in any equation. This is quite memory efficient, but it can be
very time consuming as the rhss of removed bes variables may have to be
recalculated quite often.

-H, --hashtables
use hashtables when substituting in bes equations, and translate internal
expressions to binary decision diagrams (discouraged, due to performance)

-iFORMAT, --in=FORMAT
use input format FORMAT: 'pbes' PBES in internal format 'pbes_text' PBES in
internal textual format 'text' PBES in textual (mCRL2) format 'bes' BES in internal
format 'bes_text' BES in internal textual format 'cwi' BES in CWI format 'pgsolver'
BES in PGSolver format

-oFORMAT, --out=FORMAT
use output format FORMAT: 'pbes' PBES in internal format 'pbes_text' PBES in
internal textual format 'text' PBES in textual (mCRL2) format 'bes' BES in internal
format 'bes_text' BES in internal textual format 'cwi' BES in CWI format 'pgsolver'
BES in PGSolver format

-QNUM, --qlimit=NUM
limit enumeration of quantifiers to NUM variables. (Default NUM=1000, NUM=0 for
unlimited).

-rNAME, --rewriter=NAME
use rewrite strategy NAME: 'jitty' jitty rewriting (default) 'jittyc' compiled
jitty rewriting 'jittyp' jitty rewriting with prover

-zSEARCH, --search=SEARCH
use search strategy SEARCH: 'breadth-first' Compute 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. (default)
'depth-first' Compute 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 after a larger depths. 'b' Short hand for breadth-first.
'd' Short hand for depth-first.

-sSTRAT, --strategy=STRAT
use substitution strategy STRAT: '0' Compute all boolean equations which can be
reached from the initial state, without optimization. This is is the most data
efficient option per generated equation. (default) '1' Optimize 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. '2' In
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. '3' In
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.

--timings[=FILE]
append timing measurements to FILE. Measurements are written to standard error if
no FILE is provided

-u, --unused_data
do not remove unused parts of the data specification

Standard options:

-q, --quiet
do not display warning messages

-v, --verbose
display short intermediate messages

-d, --debug
display detailed intermediate messages

--log-level=LEVEL
display intermediate messages up to and including level

-h, --help
display help information

--version
display version information
