With new theoretical insights and a specially designed computer program we were able to expand the sequence from n =18 to n = 33. New upper bounds of d(n) thought to be sharp have been obtained. ...
The classic domino exclusion problem consists of finding minimum number d(n) of dominoes on an n n chessboard to prevent placement of another domino. ...
Some generalizations
Conclusions The article contains the theorems of pure mathematics, as well as computer-assisted proofs. ...
