WebThe Robbins problem---are all Robbins algebras Boolean?---has been solved: Every Robbins algebra is Boolean. This theorem was proved automatically by EQP, a theorem proving program developed at Argonne National Laboratory. Historical Background In 1933, E. V. Huntington presented [1,2] the following basis for Boolean algebra: x + y = y + x.
