- Some time back I had posted this newsitem on the net. But unfortunately some
- problem developed in the newsfeed here and no news was coming to us. Because of
- this problem I must have lost all the responses to this item. I am posting it
- again. Please post your responses again. If, by chance, someone has collected
- responses to this item, please mail them to me.

- The basic technique used in two level minimization of single output Boolean
- functions is to find a cube cover of smallest size. My querry is about the
- estimation of the size of the cubes in the cube cover. The querry is,
-
- Given the assignment of 0, 1, and X (don't cares) to the vertices, how to
- estimate sizes of cubes in the cube cover, without actually finding the cube
- cover? Are any bounds known on the sizes of cubes in cube cover? The cube cover
- referred to here is same as the cube cover for two level minimization of
- Boolean functions.
-
- Any references are welcome.
- Thanks in advance.
