== Description ==

SDDtab is an SDD-based modal theorem prover for logics K and S4.

== Installation ==

To compile, enter 'make' in the terminal within the sddtab directory. This will create the binary bin/sddtab.  
SDDtab has been tested on both OSX and Ubuntu.

== Usage ==

SDDtab reads modal formulae from standard input with the following options:

-k	Enabled by default. Solves the benchmark in modal logic K. Mutually exclusive 
	with option -s4.  
-s4	Solves the benchmark in modal logic S4. Mutually exclusive with option -k.  
-v 	Enable verbose mode.  
-sat 	If enabled, SDDtab will decide satisfiability. If not enabled, SDDtab defaults
	to deciding validity.  
-size	SDDtab returns the size of the initial SDD constructed and does not solve
	the formulae.  
-help	Print a help message.

SDDTab accepts formulae of the form:

f :: 	prop  
	~f  
	f | f  
	f & f  
        f => f  
        f <=> f  
        <>f  
        []f  
        (f)  

where prop is an alphanumeric sequence of characters.

Example command:
cat benchmarks/k/k_branch_n/3.txt.k | bin/sddtab -v

== Benchmarking ==

The following scripts benchmark the highest instance solved and initial SDD size (respectively) for the LWB benchmark set.

benchmark2.sh  
benchmark2_size.sh

Instructions and example commands are included within the scripts as comments.
