3.7.2 Representation in Four-Dimensional Hypercube Formats
for a Computer-aided Minimization
A four dimensional hyper cube has four axes, A1-axis, A2-axis, A3 and A4-axis. It
will have 16 vertices. The origin vertex coordinates are 0000. The other coordinates
will be 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100,
1101, 1110 and 0111.
The coordinate of mid-point on a darkened axis from 1000 to 1001 is (1, 0,
0, 0.5) (An axis is darkened if there are vertices falling on it). Let us write it as
100x. Similarly, we can write, we can find other dark axes mid-points. For example, ...
