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:
-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
'bes' BES in internal format
'cwi' BES in CWI format
'pgsolver' max-parity game in PGSolver format
-oFORMAT, --out=FORMAT
use output format FORMAT:
'pbes' PBES in internal format
'bes' BES in internal format (default)
'cwi' BES in CWI format
'pgsolver' max-parity game in PGSolver format
-p[NAME], --pbes-rewriter[=NAME]
use pbes rewrite strategy NAME:
'simplify' for simplification
'quantifier-all' for eliminating all quantifiers
'quantifier-finite' for eliminating finite quantifier variables
'pfnf' for rewriting into PFNF normal form
-rNAME, --rewriter=NAME
use rewrite strategy NAME:
'jitty' for jitty rewriting (default),
'jittyc' for compiled jitty rewriting,
'jittyp' for jitty rewriting with prover
-sSTRAT, --strategy=STRAT
use strategy STRAT (default '0');
0) Compute all boolean equations which can be reached from the initial state,
without optimization (default). This is is the most data efficient option per
generated equation.
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
-t, --tree
store state in a tree (for memory efficiency)
-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
