Example Ugly Data Format Files

These are example files that you can use with the parse_magic.py script.

R6

Contains all models of R up to size 6.

R4-MN

Contains all models of a fragment of R without negation up to size 4.

R3-PN

Extends R to have necessitation with the following additional axioms:

1. p / !p
2. !(p -> q) -> (!p -> !q)
3. (!p & !q) -> !(p & q)

Output contains all satisfiable models up to size 3.

R5-S5

Extends R with axioms that classically are adequate for S5 giving rise to an R-ish version of S5 with necessitation.
