zenon - Automated theorem prover for first-order classical logic




Zenon is an automated theorem prover for first order classical logic with equality, based on the tableau method. Zenon can read input files in TPTP, Coq, Focal, and its own Zenon format. Zenon can directly generate Coq proofs (proof scripts or proof terms), which can be reinserted into Coq specifications. Zenon can also be extended.


If file is "-", it will read input from stdin.

provide context for checking the proof independently
debug mode
-errmsg <message>
prefix warnings and errors with <message>
-help, --help
print this option list and exit
-I <dir>
add <dir> to the include path (for TPTP input format)

read input file in Focal format
read input file in TPTP format
read input file in Zenon format (default)
path to Zenon's coq libraries (default /usr/share/zenon)
-max <s>[kMGT]/<i>[kMGT]/<t>[smhd]

The command:

  zenon -itptp -ocoq /usr/share/zenon*/examples/tptp-COM003+2.p
will take the input file "tptp-COM003+2.p" in TPTP format (-itptp), search for a proof, and produce any proof output in Coq format (-ocoq). tptp-COM003+2.p is a TPTP representation of the halting problem. Zenon can prove this, and will print out:
