[eclipse-clp-users] Boolean value behaviour

Dear clp users,



 Following is the script that executes:-

Script 1:



:- lib(ic).
solveNull(A,B):-

A #:: 0..1,
B #:: 0..1,

A #\= B,
B #= 1.



It provides the solution of A as 0 and B as 1 but I do not wish to have A as 0. I wish to restrict A to be var(See the script 2 below. It should pass.). One solution is to change the domain of A to 0..2 or 0..3. Is there a cleaner way of doing it?



Script 2:

:- lib(ic).
solveNull(A,B):-

A #:: 0..1,
B #:: 0..1,

A #\= B,
B #= 1,
var(A).



I am almost sure there isn't any solution to it but I wanted my search subroutine to decide the value of A.



Kindly help me.



Thanks and Regards,

Shrirang Edgaonkar
