12 e_axfilter 2.6-DEBUG "Floral Guranse"
13 This program applies SinE-like goal-directed filters to a problem spec‐
15 ification (a set of clauses and/or formulas) to generate reduced prob‐
16 lem specifications that are easier to handle for a theorem prover, but
17 still are likely to contain all the axioms necessary for a proof (if
18 one exists).
19 In default mode, the program reads a problem specification and an (op‐
21 tional) filter specification, and produces one reduced output file for
22 each filter given. Note that while all standard input formats (LOP,
23 TPTP-2 and TPTP-3 are supported, output is only and automatically in
24 TPTP-3. Also note that unlike most of the other tools in the E distri‐
25 bution, this program does not support pipe-based input and output,
26 since it uses file names generated from the input file name and filter
27 names to store the different result files

30 -h
31 --help
33 Print a short description of program usage and options.
35 -V
37 --version
39 Print the version number of the prover. Please include this with
41 all bug reports (if any).
42 -v
44 --verbose[=<arg>]
46 Verbose comments on the progress of the program. This technical
48 information is printed to stderr. The short form or the long
49 form without the optional argument is equivalent to --verbose=1.
50 -o <arg>
52 --output-file=<arg>
54 Redirect output into the named file (this affects only some out‐
56 put, as most is written to automatically generated files based
57 on the input and filter names.
58 -s
60 --silent
62 Equivalent to --output-level=0.
64 -l <arg>
66 --output-level=<arg>
68 Select an output level, greater values imply more verbose out‐
70 put.
71 -f <arg>
73 --filter=<arg>
75 Specify the filter definition file. If not set, the system will
77 uses the built-in default.
78 -S
80 --seed-symbols[=<arg>]
82 Enable artificial seeding of the axiom selection process and de‐
84 termine which symbol classes should be used to generate differ‐
85 ent sets.The argument is a string of letters, each indicating
86 one class of symbols to use. 'p' indicates predicate symbols,
87 'f' non-constant function symbols, and 'c' constants. Note that
88 this will create potentially multiple output files for each ac‐
89 tivated symbols. The short form or the long form without the op‐
90 tional argument is equivalent to --seed-symbols=p.
91 --seed-subsample[=<arg>]
93 Subsample from the set of eligible seed symbols. The argument is
95 a one-character designator for the method ('m' uses the symbols
96 that occur in the most input formulas, 'l' uses the symbols that
97 occur in the least number of formulas, and 'r' samples ran‐
98 domly), followed by the number of symbols to select. The option
99 without the optional argument is equivalent to --seed-subsam‐
100 ple=r1000.
101 -m
103 --seed-method[=<arg>]
105 Specify how to select seed axioms when artificially seeding is
107 used.The argument is a string of letters, each indicating one
108 method to use. The letters are: 'l': use the syntactically
109 largest axiom in which the seed symbol occurs. 'd': use the
110 most diverse axiom in which the seed symbol occurs, i.e. the
111 symbol with the largest set of different symbols. 'a': use all
112 axioms in which the seed symbol occurs. For 'l' and 'd', if
113 there are multiple candidates, use the first one.If the option
114 is not set, 'a' is assumed. The short form or the long form
115 without the optional argument is equivalent to
116 --seed-method=lda.
117 -d
119 --dump-filter
121 Print the filter definition in force.
123 --lop-in
125 Set E-LOP as the input format. If no input format is selected by
127 this or one of the following options, E will guess the input
128 format based on the first token. It will almost always correctly
129 recognize TPTP-3, but it may misidentify E-LOP files that use
130 TPTP meta-identifiers as logical symbols.
131 --lop-format
133 Equivalent to --lop-in.
135 --tptp-in
137 Parse TPTP-2 format instead of E-LOP (but note that includes are
139 handled according to TPTP-3 semantics).
140 --tptp-format
142 Equivalent to --tptp-in.
144 --tptp2-in
146 Synonymous with --tptp-in.
148 --tptp2-format
150 Synonymous with --tptp-in.
152 --tstp-in
154 Parse TPTP-3 format instead of E-LOP (Note that TPTP-3 syntax is
156 still under development, and the version in E may not be fully
157 conforming at all times. E works on all TPTP 6.3.0 FOF and CNF
158 input files (including includes).
159 --tstp-format
161 Equivalent to --tstp-in.
163 --tptp3-in
165 Synonymous with --tstp-in.
167 --tptp3-format
169 Synonymous with --tstp-in.

173 Report bugs to <schulz@eprover.org>. Please include the following, if
174 possible:
175 * The version of the package as reported by eprover --version.
177 * The operating system and version.
179 * The exact command line that leads to the unexpected behaviour.
181 * A description of what you expected and what actually happend.
183 * If possible all input files necessary to reproduce the bug.
