pbesparelm
The purpose of this tool is to find those parameters in parameterised Boolean equation sytems that do not affect the solution, and remove those in a similar fashion as lpsparelm.
Example:
Instantiation of this PBES using tools such as pbes2bool or pbessolve does not terminate. However, in this PBES, parameter 
of both equations is redundant (it does not appear positively in any equation), and can be removed. The resulting PBES will be:
The algorithm underlying the tool is described in detail in [OWW09].
Usage
pbesparelm [OPTION]... [INFILE [OUTFILE]]
Description
Reads a file containing a PBES, and applies parameter elimination to it. If OUTFILE is not present, standard output is used. If INFILE is not present, standard input is used.
Command line options
-iFORMAT , --in=FORMAT
use input format FORMAT:
pbesPBES in internal format
pgsolverBES in PGSolver format
textPBES in textual (mCRL2) format
-oFORMAT , --out=FORMAT
use output format FORMAT:
besBES in internal format
pbesPBES in internal format
pgsolverBES in PGSolver format
textPBES in textual (mCRL2) format
--timings[=FILE]
append timing measurements to FILE. Measurements are written to standard error if no FILE is provided
