Hi Kish,

This was extremely helpful to me.  I changed my code and did increase
the efficiency of my algorithm.  My question now however is the
get_domain function.  I try this:

ic_sets:(T1::[]..[1,2,3,4,5]), writeln(T1), T2 in T1, writeln(T2),
ic:(get_domain(T2, T3)), writeln(T3), ic:(T4::1..5), writeln(T4).

The ideas is to turn T1 into an ic dom variable.  The output of this program is:

T1{([] .. [1, 2, 3, 4, 5]) : _604{0 .. 5}}
T2{1 .. 5}
1 .. 5
T4{0 .. 5}

It appears that T3 and T4 are not the same kind of variable.  Is that true?

P.S.

My code is evolving at:

Please feel free to make other suggestions!  I can't even tell you in
words how grateful I am for this help.
