How to use:
All programs are self-contained, hopefully. Try first a sample
session in each program to get familiar with a model.
Comment:
The above programs contain no negation. When a program contains
negation, you have to compile away negation by FOC (first order
compiler). For PRISM programs with negation, see ../exs_fail.
