Synopsis

lpsconstelm[OPTION]... [INFILE [OUTFILE]]

Short Description

Remove constant process parameters from the LPS in INFILE and write the result to OUTFILE. If INFILE is not present, standard input is used. If OUTFILE is not present, standard output is used.

If it can be determined that certain parameters of this LPS remain constant throughout any run of the process, all occurrences of these process parameter are replaced by the initial value and the process parameters are removed from the LPS.

If the initial value of a process parameter is a global variable and remains a global variable throughout the run of the process, the process variable is considered constant.

If the initial value of a process parameter is a global variable and is only changed once to a certain value, the process parameter is constant and the specific value is used for substitution.

Options

OPTION can be any of the following:

-c, --ignore-conditions

ignore conditions by assuming they evaluate to true

-f, --instantiate-free-variables

allow free variables to be instantiated as a side effect of the algorithm

NOTE: this functionality is untested!

-s, --remove-singleton-sorts

remove parameters with single element sorts

-t, --remove-trivial-summands

remove summands with condition false

-rNAME, --rewriter=NAME

use rewrite strategy NAME:

 'jitty' for jitty rewriting (default),
 'jittyp' for jitty rewriting with prover,
 'jittyc' for compiled jitty rewriting,
 'inner' for innermost rewriting,
 'innerp' for innermost rewriting with prover, or
 'innerc' for compiled innermost rewriting

--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

-h, --help

display help information

--version

display version information
