Equivalence Verification for Disjunctive Logic Programs


[Background] [Examples] [References] [Using the software] [Download] [Back to LPEQ]


The translator dlpeq is an implementation of the method for verification of weak equivalence of disjunctive logic programs in [OJ, LPNMR'04]. It is designed to be used with GnT and the front-end lparse (pre 1.0.14) which are available here. If you use lparse 1.0.14 or later, use dencode to switch to the old format.

Using the Software

dlpeq is used as follows in order to check the equivalence of program1.lp and program2.lp:
lparse --dlp program1.lp >
lparse --dlp program2.lp >
Either using one-phased or two-phased translation:

dlpeq | gnt 1
dlpeq | gnt 1
dlpeq -p 1 | gnt 1
dlpeq -p 1 | gnt 1
dlpeq -p 2 | gnt 1
dlpeq -p 2 | gnt 1

More examples of the usage of dlpeq can be found here.
