Computer sayansi: tebulo choonadi. Kupanga matebulo choonadi

Today ife kulankhula za nkhani wotchedwa sayansi. Choonadi tebulo, zosiyanasiyana ntchito, dongosolo la kuphedwa - awa ndi mafunso athu omwe tidzayesetsa kupeza mayankho mu nkhani.

Kawirikawiri Maphunzirowa chimaphunzitsidwa sekondale, koma ophunzira ambiri chifukwa chosamvetsa zina. Ndipo ngati mukupita kuti adzipereke moyo wanga, izo basi simungakhoze kuchita popanda kuika umodzi mayeso boma sayansi kompyuta. Tebulo choonadi, akatembenuka mawu ovuta, mavuto chisankho mfundo - akhoza kukumana ndi tikiti onse. Tikambirana mwatsatanetsatane nkhani imeneyi ndi kukuthandizani kupeza mipira kwambiri pa mayeso.

nzeru yake ya nkhani

Kodi mtundu wa nkhani - kompyuta sayansi? Tebulo choonadi - moimangila? Chifukwa sayansi ndi mfundo za? Mafunso onsewa, ife adzayankha inu tsopano.

luso Information - ziri ndithu nkhani zochititsa chidwi. Zingakhale zovuta anthu masiku ano, chifukwa chirichonse chomwe paliponse, mwanjira ina, zokhudzana kompyuta.

Chikhazikitso cha mfundo za sayansi ndi aphunzitsi kusukulu ya sekondale ku maphunziro sayansi. Choonadi matebulo, ntchito, kusintha mawu - zonsezi ayenera kufotokozera mphunzitsi wa sayansi kompyuta. sayansi n'kofunika kwambiri pa moyo wathu. Kuyang'anitsitsa, chirichonse umamumvera lamulo lirilonse. Munabzala mpira, iyo inawuluka, koma ndiye anagwa ku dziko lapansi, chinali chifukwa cha malamulo a sayansi ndi mphamvu yokoka. Amayi akamaphika msuzi ndi kuwonjezera mchere. Chifukwa pamene ife kudya, tilibe inadza mbewu? Ndithu chabe, mchere kusungunuka m'madzi, kumvera malamulo zimapangidwira.

Tsopano kulabadira momwe inu kulankhula.

• "Ngati ine nditi kutenga mphaka wanu ku chipatala Chowona Zanyama, ndiye kuti katemera."
• "Lero tsiku zovuta, chifukwa iwe onani."
• "Ine sindikufuna kuti ndipite ku yunivesite, chifukwa lero adzakhala colloquium", ndi zina zotero.

Chirichonse chimene inu mukuti, onetsetsani kuti kumvera malamulo a maganizo. Zimenezi zikugwira onse malonda ndi wocheza. Pachifukwa ichi m'pofunika kumvetsa malamulo maganizo, osati kuchita zinthu mwachisawawa, ndi kukhulupirira mu zisachitike.

ntchito

Pofuna kuti tebulo choonadi ntchito akufuna muyenera kudziwa ntchito mfundo zomveka. Ndi chiyani icho? Zomveka ntchito ali ndi zosintha, amene mawu (zoona kapena zabodza), ndi mtengo wa ntchito chiyenera kutipatsa yankho ku funso lakuti: ". Mawu amenewa ndi zoona kapena zabodza"

mawu onse ndi mfundo zotsatirazi:

• Zoona kapena zonama.
• T kapena F.
• 1 kapena 0.
• Plus kapena opanda.

Apa, kupereka mmalo njira yomwe ndi yabwino kwa inu. Pofuna kuti tebulo choonadi, tiyenera kutchula osakaniza onse zosintha. chiwerengero chawo masamu mfundo: 2 mphamvu N. The chifukwa cha mawerengedwe - chiwerengero cha ma zotheka wa N variable mu njira amatanthauza chiwerengero cha zosintha mu chikhalidwe. Ngati akuti ali zambiri zosintha, mungathe kugwiritsa ntchito Chiwerengero nokha kapena tebulo kakang'ono ndi erection awiri kuti mphamvu.

Nchito zonse mfundo ndi nsinga seveni kapena yolumikiza mawu akuti:

• Chulutsa (molumikizana).
• Kuwonjezera (disjunction).
• Corollary (tionetsa).
• Pazikhala kufanana.
• Inversion.
• Sheffer sitiroko.
• Pierce muvi.

Opaleshoni yoyamba, akuimira mu mndandanda, amatchedwa "zomveka chulutsa." Mwachitsanzo momveka mu mawonekedwe a kukalowa mudzichonga, zizindikiro & kapena *. Sitepe yachiwiri ku mndandanda - zomveka Komanso, zimaonetsa akuonetsedwa ngati bango +. Apa nkhani Motero, chomwenso ndi muvi akuloza ku zinthu pa pofufuza. Pazikhala kufanana ndi amaimira ziwiri muvi, ntchito ali ndi phindu lenileni pokha pokha za ndondomekozi makhalidwe onse kutenga mtengo wa "1" kapena "0". Inversion ndi zomveka negation. Sheffer sitiroko ntchito akutchedwa, amene akana molumikizana ndi zomveka kapena - ntchito, negating ndi disjunction.

Kuweta ntchito bayinare

Kukamba zoona tebulo kumathandiza kupeza yankho vuto, koma muyenera kukumbukira tebulo ntchito bayinare. M'chigawo chino, iwo kuperekedwa.

Molumikizana (chulutsa). Ngati mawu awiri ndi woona, chifukwa ife kupeza choonadi, zina zonse ife bodza.

Izo zikuwoneka ngati tebulo, inu mukudziwa, ndiye palibe kubweretsa izo kwa mitunduyi onse. Mu chithunzi pamwambapa mukuonera zina, chifukwa ndi wofanana ndi munthu.

Zotsatira - kugona pa zomveka Kuwonjezera ndife Koma ngati zolowetsa ziwiri zonama.

The zomveka chifukwa chifukwa onyenga kokha pamene chikhalidwe chiri choona, monga chotsatira - bodza. Mungapereke chitsanzo pa moyo: "Ndinafuna kugula shuga, koma shopu chinatsekedwa" Choncho, shuga ndi sanaiwombole.

Pazikhala kufanana ndi zoona zokha pa nkhani ya makhalidwe athandizira zofanana. Ndiko kuti, pamene awiriawiri "0, 0" kapena "1 1".

Pankhani ya inversion kupulayimale, ngati athandizira ndi mawu oona, anatembenukira kwa wabodza, ndi mosemphanitsa. Mu M'chithunzithunzi munakwanisa kuona mmene anasonyeza momveka.

Schiffer bala linanena bungwe adzakhala ndi chifukwa zabodza pokhapokha ngati pali ziŵiri kwenikweni.

Pankhani ya ntchito zomveka kapena adzakwaniritsidwa okha ngati athandizira tili chabe mawu abodza.

Kuti chimene kuchita ntchito zomveka

Onani kuti pomanga matebulo choonadi ndi zosabvuta pa mawu zimatheka pamene m'ndondomeko ntchito. Kumbukirani akuyambira imene ayenera kuchitidwa, ndikofunika kuti zotsatira zolondola.

• zomveka negation;
• chulutsa;
• Kuwonjezera;
• zofufuza;
• pazikhala kufanana;
• kukana chulutsa (Sheffer sitiroko);
• kukana Kuwonjezera (arrow Pierce).

Mwachitsanzo №1

Ife tsopano akamufunsirire tione chitsanzo cha kumanga tebulo choonadi kwa 4 zosintha. Muyenera kudziwa zomwe milandu F = 0 mu aone kuti pali kuti: Nea + B + C * D

Yankho ntchito imeneyi zidzakhala kulanda osakaniza: "1, 0, 0, 0", "1, 0, 0 1" ndi "1, 0 1, 0". Monga mukuonera, kupanga tebulo ndithu chabe choonadi. Apanso Ndikufuna kuweruza dongosolo la ntchito. Ngati zenizeni, izo zinali motere:

1. The inversion za mfundo yoyamba.
2. The molumikizana la mawu wachitatu ndi wachinayi.
3. Disjunction akuti chachiwiri ndi zotsatira za kuwerengetsera m'mbuyomu.

Mwachitsanzo №2

Tsopano ife tiyang'ana pa ntchito ina imene imafuna yomanga tebulo choonadi. Kompyuta (zitsanzo unatengedwa kuchokera Maphunziro) mwina mavuto zomveka buku. Kuona mwachidule mmodzi wa iwo. Kodi Vanya mlandu wakuba mpira, ngati inu mukudziwa zotsatirazi:

• Ngati Vanya kuba kapena kuba Peter, ndiye Sergei nawo kuba.
• Ngati Ivan si wolakwa, ndipo Sergei kuba mpira.

Ife anayamba kalembedwe: I - Ivan anaba mpirawo; P - Peter anaba; C - Sergei anaba.

Mu chikhalidwe ichi, tingapange anthu aone kuti pali: F = ((Nei + R) tionetsa C) * (Nei tionetsa HEC). Tiyenera options anthu, kumene ntchito amatenga mtengo weniweni. Kenako, jambulani tebulo, chifukwa ntchito izi mochuluka monga 7 kanthu, adzakhululukidwa zasiyidwa. Ife adzapatsidwa yekha ndi deta athandizira ndi zotsatira.

Tawonani kuti mu ntchitoyi tinagwiritsira ntchito pamodzi ndi kuchepetsa mmalo mwa zizindikiro "0" ndi "1". Izi ndizovomerezeka. Tili ndi chidwi ndi kuphatikiza komwe F = +. Kuzifufuza, titha kupeza mfundo yotsatirayi: Vanya adagwira nawo ntchito kuba, chifukwa nthawi zonse F amatengera mtengo, ndipo ali ndi mtengo wabwino.

Chitsanzo №3

Tsopano tikukupatsani kuti mupeze mayina a F = 1. The equation ili ndi fomu yotsatira: F = neA + B * A + neB. Timasonkhanitsa patebulo la choonadi:

Yankho: kuphatikiza 4.
