ltlgrind − list mutations of a formula.
ltlgrind [OPTION...] [FILENAME[/COL]...]
List formulas that are similar to but simpler than a given formula.
−f, −−formula=STRING
process the formula STRING
−F, −−file=FILENAME[/COL]
process each line of FILENAME as a formula; if COL is a positive integer, assume a CSV file and read column COL; use a negative COL to drop the first line of the CSV file
−−lbt−input
read all formulas using LBT’s prefix syntax
−−lenient
parenthesized blocks that cannot be parsed as subformulas are considered as atomic properties
−−ap−to−const
atomic propositions are replaced with true/false
−−remove−multop−operands
remove one operand from multops
−−remove−one−ap
all occurrences of an atomic proposition are replaced with another atomic proposition used in the formula
−−remove−ops
replace unary/binary operators with one of their operands
−−rewrite−ops
rewrite operators that have a semantically simpler form: a U b becomes a W b, etc.
−−simplify−bounds
on a bounded unary operator, decrement one of the bounds, or set min to 0 or max to unbounded
−−split−ops
when an operator can be expressed as a conjunction/disjunction using simpler operators, each term of the conjunction/disjunction is a mutation. e.g. a <−> b can be written as ((a & b) | (!a & !b)) or as ((a −> b) & (b −> a)) so those four terms can be a mutation of a <−> b
−m, −−mutations=NUM
number of mutations to apply to the formulae (default: 1)
−n, −−max−count=NUM
maximum number of mutations to output
−−sort |
sort the result by formula size |
−0, −−zero−terminated−output
separate output formulas with \0 instead of \n (for use with xargs −0)
−8, −−utf8
output using UTF−8 characters
−−format=FORMAT
specify how each line should be output (default: "%f")
−l, −−lbt
output in LBT’s syntax
−−latex
output using LaTeX macros
−o, −−output=FORMAT
send output to a file named FORMAT instead of standard output. The first formula sent to a file truncates it unless FORMAT starts with ’>>’.
−p, −−full−parentheses
output fully−parenthesized formulas
−s, −−spin
output in Spin’s syntax
−−spot |
output in Spot’s syntax (default) |
−−wring
output in Wring’s syntax
The FORMAT string passed to −−format may use the following interpreted sequences:
%< |
the part of the line before the formula if it comes from a column extracted from a CSV file | ||
%> |
the part of the line after the formula if it comes from a column extracted from a CSV file | ||
%% |
a single % | ||
%a |
number of atomic propositions used in the formula | ||
%b |
the Boolean−length of the formula (i.e., all Boolean subformulas count as 1) | ||
%f |
the formula (in the selected syntax) | ||
%F |
the name of the input file |
%h, %[vw]h
the class of the formula is the Manna−Pnueli hierarchy ([v] replaces abbreviations by class names, [w] for all compatible classes)
%L |
the original line number in the input file |
|||
%s |
the length (or size) of the formula |
−−help |
print this help |
−−version
print program version
Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.
