in thread decomposing binary matrices

B can't be 4. A or E must be 4. Which ever one is 4, the other must be 2 but B can never be 4.

If I have understood the problem correctly, any time N variables can only be the same N values, they can be extracted from the matrix. This process is repeated until you are left with a "left over" matrix. Presumably this reduces the amount of brute force necessary to find values.

This also sounds like a job best solved by Prolog or some other logic programming language as we are trying to searching to satisfy constraints.

    Thanks, I have not seen the 'each property have a distinct value' constraint... :>)
