Here is some useful code if you want to do your own empirical analysis of decision procedure for modal logic:
LISP code for generating hard random modal formulae according to the guidelines given in the MPII research report 97-2-003. (Version 1.2)
SICStus Prolog code for the functional translation of modal formulae.
SICStus Prolog code for simplifying modal formulae.
oft.tgz (Version 1.4)
A small collection of files to use the functional translation approach. Requires FLOTTER, SPASS, CLISP, SICStus Prolog, and Perl.
