11. Furthermore, every possible input-output behavior can be modeled by a suitable Boolean expression . 12. Fault tree methodology employs boolean expressions to gate conditions when parent nodes are satisfied by leaf nodes. 13. Python allows boolean expressions with multiple equality relations in a manner that is consistent with general use in mathematics. 14. Further, VSIDS guarantees that each variable assignment satisfies the greatest number of recently searched segments of the Boolean expression . 15. Do you want to abort the check on each Boolean expression after one combo is found which evaluates as T? 16. A case statement could be used to quickly select the desired Boolean expression to test, inside the innermost loop. 17. Abductive inference starts with a set of facts " F " which is a statement ( Boolean expression ). 18. As VSIDS progresses and searches more parts of the Boolean expression , periodically, all scores are divided by a constant. 19. Next, from each decision matrix we form a set of Boolean expressions , one expression for each row of the matrix. 20. Their basic premise is to choose a free variable assignment that will satisfy the most already unsatisfied clauses in the Boolean expression .
