check a boolean formula

NAME

formulacheck - check a boolean formula

SYNOPSIS

formulacheck [OPTION]... [INFILE]

DESCRIPTION

Checks whether the boolean formula (an mCRL2 data expression of sort Bool) in INFILE holds. If INFILE is not present, stdin is used.

OPTIONS

OPTION can be any of the following:
-c, --counter-example

display a valuation for which the formula does not hold, in case it is neither a contradiction nor a tautology

-o, --induction

apply induction on lists

-pPREFIX, --print-dot=PREFIX

save a .dot file of the resulting BDD if it is impossible to determine whether the formula is a contradiction or a tautology; PREFIX will be used as prefix of the output files

-rNAME, --rewriter=NAME

use rewrite strategy NAME:
'jitty' for jitty rewriting (default),
'jittyc' for compiled jitty rewriting,
'jittyp' for jitty rewriting with prover

-zSOLVER, --smt-solver=SOLVER

use SOLVER to remove inconsistent paths from the internally used BDDs (by default, no path elimination is applied):
'cvc' for the SMT solver CVC3

-sSPECFILE, --spec=SPECFILE

check the formula against the data types from the LPS or PBES in SPECFILE

-tLIMIT, --time-limit=LIMIT

spend at most LIMIT seconds on proving a single formula

--timings[=FILE]

append timing measurements to FILE. Measurements are written to standard error if no FILE is provided

-w, --witness

display a valuation for which the formula holds, in case it is neither a contradiction nor a tautology

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
