Sep 7, 2020 at 18:51 comment added sergiu reznicencu Or better. Just assume the final result contains all inputs used once with one operator in between. This is very much possible
Sep 7, 2020 at 18:49 comment added sergiu reznicencu Brute force would be cool. I wonder if some optimization algorithm could be found for minimizing the number of operators used. Some kind of derivative for this problem? Perhaps AI?
Sep 7, 2020 at 17:57 comment added Sean @Ski Mask, I was actually asking out of my own interest, and I'm still interested in the answer!

Sep 7, 2020 at 11:19 comment added Ski Mask @Sean Unfortunately this is from a written question from a past paper. So I have to show all my working out and the laws that I used.

Sep 5, 2020 at 22:04 comment added Sean Are there any solver tools that can brute-force (or use other heuristics to obtain) a solution to this sort of problem?

Sep 4, 2020 at 21:50 comment added cjferes Seems like $$A\equiv B$$ is the same as $$\overline{(A\oplus B)}$$. In that case, $$\begin{align} Z&=\overline{C_i} (A \oplus B) + C_i (A\equiv B)\\ &=\overline{C_i} (A \oplus B) + C_i\overline{(A \oplus B)} \\ &= C_i \oplus (A\oplus B)\\ &=A\oplus B\oplus C_i \end{align}$$
Sep 4, 2020 at 19:10 comment added edmz By \$X\equiv Y \$, what do you mean exactly? I've never seen this notation so far.

Sep 3, 2020 at 12:44 comment added Ski Mask Wouldn't it be (NOT X AND Y) OR (X AND Y)?
Sep 3, 2020 at 12:07 comment added jcaron It's another instance of (X AND NOT Y) OR (NOT X AND Y) = X XOR Y, with X being Ci here and Y being A XOR B.
Sep 3, 2020 at 12:02 comment added Ski Mask @jcaron Yes but I'm trying to figure out why $$\bar C_i(A \oplus B) + C_i(A \equiv B)=A \oplus B \oplus C_i$$.
Sep 2, 2020 at 21:05 comment added jcaron $$A \equiv B$$ is the same as NOT $${(A \oplus B)}$$ (sorry not very good at formulas)
