Hauv lwm lo lus, Boolean multiplication sib raug rau qhov kev ua haujlwm ntawm lub rooj vag "AND", nrog rau kev sib txuas lus sib txuas: Zoo li "ib txwm" algebra, Boolean algebra siv cov tsiaj ntawv alphabetical rau denotevariables. Piv txwv li, yog tias qhov sib txawv "A" muaj tus nqi ntawm 0, ces qhov sib ntxiv ntawm A muaj tus nqi ntawm 1.
Dhau li ntawm no, dab tsi yog Boolean khoom?
Cov khoom siv Boolean yog txhais los ntawm "* ", " ˆ ", los yog "AND". Cov khoom yog nyob rau hauv ib txoj kev opposite ntawm boolean sum. Ob leeg x thiab y yuav tsum muaj tseeb thiaj li yuav daws tau qhov tseeb. Lwm daim ntawv ua qhov tsis muaj tseeb.
Tsis tas li ntawd, koj yuav nrhiav tau cov lus qhia Boolean li cas? Txoj cai ntawm Boolean Algebra
- Txoj Cai Ideempotent. A * A = A. A + A = A.
- Associative Law. (A * B) * C = A * (B * C) (A + B) + C = A + (B + C)
- Kev cai lij choj. A*B = B*A.
- Txoj cai faib. A * (B + C) = A * B + A * C.
- Txoj Cai Qhia Txog Tus Kheej. A * 0 = 0 A * 1 = A.
- Txoj Cai Ntxiv. A * ~A = 0.
- Txoj Cai Involution. ~(~A) = A.
- DeMorgan Txoj Cai. ~(A*B) = ~A + ~B.
Ntxiv mus, dab tsi yog Boolean qhia nrog piv txwv?
A boolean kev qhia yog ib kev qhia uas tshwm sim hauv ib boolean tus nqi, uas yog, nyob rau hauv ib tug nqi ntawm qhov tseeb los yog cuav. Daim ntawv println yuav raug tua yog tias ntub thiab txias yog qhov tseeb, lossis yog tias cov neeg pluag thiab tshaib plab yog qhov tseeb. Booleanexpressions feem ntau yog siv raws li tej yam kev mob (raws li nyob rau hauv lub piv txwv saum toj no).
Boolean logic siv rau dab tsi?
Cov kev pab cuam siv kev sib piv yooj yim los pab txiav txim siab. Boolean logic yog formof algebra qhov twg tag nrho cov txiaj ntsig yog qhov tseeb lossis cuav. Cov txiaj ntsig ntawm qhov tseeb thiab tsis tseeb yog siv los soj ntsuam cov xwm txheej uas xaiv thiab iteration yog nyob ib ncig ntawm.
