NAME

       mcrl22lps - translate an mCRL2 specification to an LPS

SYNOPSIS

       mcrl22lps [OPTION]... [INFILE [OUTFILE]]

DESCRIPTION

       Linearises  the  mCRL2 specification in INFILE and writes the resulting LPS to OUTFILE. If
       OUTFILE is not present, stdout is used. If INFILE is not present, stdin is used.

OPTIONS

       OPTION can be any of the following:

       -b, --binary
              when clustering use binary case functions instead of  n-ary;  in  the  presence  of
              -w/--newstate, state variables are encoded by a vector of boolean variables

       -e, --check-only
              check syntax and static semantics; do not linearise

       -c, --cluster
              all actions in the final LPS are clustered. Clustering means that summands with the
              same action labels are grouped together. For instance, a(f1)  .  P(g1)  +  a(f2)  .
              P(g2)  is  replaced  by  sum  b:  Bool  . a(if(b, f1, f2)) . P(if(b, f2, g2)).  The
              advantage is that the number of summands can be reduced subtantially in  this  way.
              The  disadvantage  is  that  sum  operators  are introduced and new data sorts with
              auxiliary functions are generated. In order to avoid the generation of  new  sorts,
              the option -b/--binary can be used.

       -D, --delta
              add a true->delta summands to each state in each process; these delta's subsume all
              other conditional timed delta's, effectively reducing the number of delta  summands
              drastically  in the resulting linear process; speeds up linearisation.  This is the
              default, but it does not deal correctly with time.

       -lNAME, --lin-method=NAME
              use linearisation method NAME: 'regular' for generating  an  LPS  in  regular  form
              (specification  should  be regular) (default) 'regular2' for a variant of 'regular'
              that uses more data variables (useful when 'regular' does  not  work)  'stack'  for
              using stack data types (useful when 'regular' and 'regular2' do not work)

       -w, --newstate
              state  variables  are  encoded  using  enumerated types instead of positive natural
              numbers (Pos). By using this option new finite  sorts  named  Enumk  are  generated
              where  k  is  the size of the domain. Also, auxiliary case functions and equalities
              are defined. In combination with the option --binary the finite sorts  are  encoded
              by booleans. (requires linearisation method 'regular' or 'regular2').

       -z, --no-alpha
              alphabet  reductions  are  not  applied.By default mcrl22lps attempts to distribute
              communication, hiding and allow operators over the parallel composition operator as
              this  reduces the size of intermediate linear processes. By using this option, this
              step can be avoided. The name stems from the alphabet axioms in process algebra.

       -n, --no-cluster
              the actions in intermediate LPSs are not clustered before they are put in parallel.
              By  default  these  processes  are  clustered  to  avoid a blow-up in the number of
              summands when transforming two parallel  linear  processes  into  a  single  linear
              process.  If  a  linear  process  with  M summands is put in parallel with a linear
              process with N summands the resulting process has M×N + M + N summands. Both M  and
              N  can  be substantially reduced by clustering at the cost of introducing new sorts
              and functions. See -c/--cluster, esp. for a short  explanation  of  the  clustering
              process.

       --no-constelm
              do not try to apply constant elimination when generating a linear process.

       -g, --no-deltaelm
              avoid  removing  spurious  delta  summands.  Due  to  the  existence of time, delta
              summands cannot be omitted. Due to the presence  of  multi-actions  the  number  of
              summands  can  be  huge.  The algorithm for removing delta summands simply works by
              comparing each delta summand with each other summand to see whether  the  condition
              of  the  one  implies  the  condition  of  the  other.  Clearly, this has quadratic
              complexity, and can take a long time.

       -f, --no-globvars
              instantiate don't care values with arbitrary constants, instead of  modelling  them
              by global variables. This has no effecton global variables that are declared in the
              specification.

       -o, --no-rewrite
              do not rewrite data terms while linearising; useful when the  rewrite  system  does
              not   terminate.  This  option  also  switches  off  the  application  of  constant
              elimination.

       -m, --no-sumelm
              avoid applying sum elimination in parallel composition

       -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

       -a, --statenames
              the names of generated data parameters are extended with the name of the process in
              which they occur. This makes it easier to determine where the parameter comes from.

       -T, --timed
              Translate  the process to linear form preserving all timed information. In parallel
              processes the number of possible  time  constraints  can  be  large,  slowing  down
              linearisation. Confer the --delta option which yiels a much faster translation that
              does not preserve timing correctly

       --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
