lpsconfcheck1

Usage

Overview

Checks which tau-summands of the mCRL2 LPS in INFILE are confluent, marks them by renaming them to ctau, and write the result 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:

-a, --check-all

check the confluence of tau-summands regarding all other summands, instead of continuing with the next tau-summand as soon as a summand is encountered that is not confluent with the current tau-summand

-c, --counter-example

display a valuation for which the confluence condition does not hold, in case the encountered condition is neither a contradiction nor a tautolgy

-g, --generate-invariants

try to prove that the reduced confluence condition is an invariant of the LPS, in case the confluence condition is not a tautology

-o, --induction

apply induction on lists

-iINVFILE, --invariant=INVFILE

use the boolean formula (an mCRL2 data expression of sort Bool) in INVFILE as invariant

-n, --no-check

do not check if the invariant holds before checking for for confluence

-m, --no-marking

do not mark the confluent tau-summands; since there are no changes made to the LPS, nothing is written to OUTFILE

-pPREFIX, --print-dot=PREFIX

save a .dot file of the resulting BDD in case two summands cannot be proven confluent; PREFIX will be used as prefix of the output files

-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

-zSOLVER, --smt-solver=SOLVER

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

-sNUM, --summand=NUM

eliminate or simplify the summand with number NUM only

-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

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
