# pbesconstelm(1)

remove constant parameters from a PBES

## NAME

pbesconstelm - remove constant parameters from a PBES

## SYNOPSIS

**pbesconstelm** \[*OPTION*\]... \[*INFILE* \[*OUTFILE*\]\]

## DESCRIPTION

Reads a file containing a PBES, and applies constant parameter elimination to  it. If OUTFILE is not present, standard output is used. If INFILE is not  present, standard input is used.

## OPTIONS

- *OPTION* can be any of the following:

  - **-c**, **--compute-conditions**

  compute propagation conditions

- **-i***FORMAT*, **--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

- **-o***FORMAT*, **--out**=*FORMAT*

  use output format FORMAT: 'pbes' PBES in internal format 'pbes\_text' PBES in internal textual format 'text' PBES in textual (mCRL2) format

- **-p***NAME*, **--pbes-rewriter**=*NAME*

  use pbes rewrite strategy NAME: 'simplify' for simplification (default) 'quantifier-all' for eliminating all quantifiers 'quantifier-finite' for eliminating finite quantifier variables 'pfnf' for rewriting into PFNF normal form 'ppg' for rewriting into Parameterised Parity Game form 'bqnf-quantifier' for rewriting quantifiers over conjuncts to conjuncts of  quantifiers (experimental)

- **-Q***NUM*, **--qlimit**=*NUM*

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

- **-e**, **--remove-equations**

  remove redundant equations

- **-r***NAME*, **--rewriter**=*NAME*

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

- **--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
