Ukukhetha Uhlobo

Enye yezindlela ezibaluleke ukusebenza idatha kuhlungwa. Elisetshenziswa hhayi kuphela ngokushesha, kodwa futhi lula kakhulu ezidingekayo futhi ezibalulekile inqubo izinhlelo. Unciphise zakhukhula lo mqondo e phakathi program kuyinto ukuhleleka amarekhodi e-database.

izindlela Ukuhlunga ehambisana kuze kube yilolu suku, nakuba intuthuko kwezobuchwepheshe ahlanganiswe nezindlela zanamuhla yokusebenza nemishini computer. Abadume emkhakheni usosayensi yakhe D. Knuth uthi cishe ingxenye yabantu isikhathi ukusebenza kwimininingo kucutshungulwa matasa ukuhlunga kubo. Uveza izizathu ezintathu ezichaza le nkambo izenzakalo:

1. Ukukhethwa Uhlobo nezinye izindlela isetshenziswa kabanzi kakhulu.
2. algorithm yayo livame ukusetshenziswa ngaphandle izidingo ezikhethekile.
3. Ukuze kufezeke izinhloso wasebenzisa imodeli abangaphelele.

Ukuze asheshise ukucutshungulwa idatha, okokuqala udinga ukuthola ikhambi lalezi zinkinga. Program uzama ukudala isakhiwo ukuthi ngabe ngokwalo belingenakukwazi ukuyiqukatha zisebenzisa algorithm lapho kudingeka. Uma wadala, ukuphuthumisa kakhulu umsebenzi nge yenqwaba idatha futhi kuyoba khona ukunyuswa-ukonga Computing imithombo. Kodwa kuze lokho kwenzeka, futhi sizobheka izindlela ezikhona njengamanje ukuhlunga.

Bonke zihlukaniswe zangaphakathi nezangaphandle. Ingqikithi yalo Indlela yokuqala ukuthi wonke amarekhodi ihlelwa, ibekwe ikhumbule umshini. Kodwa lapho akudingi zangaphandle ekuhlungeni izinqubo, futhi ngokuvamile zisekelwe ngowokuqala yalezi zindlela, nezinye izithasiselo ezincane kuphela.

Hlunga kukho, okuzoxoxwa iphathelene ngaphakathi. Kuyadingeka ukuba ayeke kuso kabanzi, njengoba lokhu hlobo lokucubungula ikuvumela ukuhlunga kalula kakhudlwana futhi inzuzo. izindlela wakhe zihlukaniswe 4 amaqembu ayinhloko:

1. uhlobo Ukufakwa.
2. ngokubala ukucubungula.
3. inqubo Exchange.
4. Ukukhethwa Uhlobo.

Kufanele kuqashelwe ukuthi awukho umahluko ocacile phakathi kwalezi zinto zombili, basuke eduze okwakuthandelene futhi zifana kakhulu nomunye. Lokhu kuholela ukuba khona ukuxhumana elinqunyiwe umsebenzi wabo. Isibonelo elula yokusebenza processing idatha kwenza ukuhlunga nokubala. Kunjengokungathi ngesisekelo abanye, kodwa namuhla kuyaqabukela asetshenziswa. Enye indlela - faka - kubaluleke kakhulu. Umbono wakhe ukuthi ngokuqondile ukhiye ibekwe esihlalweni eyabelwe kuso. Kodwa lapha kukhona eziningi izimo futhi Uphatha kabi umsebenzi inombolo enkulu amarekhodi. Abaningi izindlela elikhiqizayo kakhulu processing idatha zikhona Exchange Uhlobo. Ethandwa kakhulu sobala kuleli qembu - indlela lokho okubizwa ngomlobokazi bubble. Umsebenzi kusekelwe algorithm ezilandelayo: ukuqhathanisa okuqoshiwe ngokulandelana kwenziwe njalo futhi, uma inani wokuqala wabo ngaphezulu ke basuke nje emuva. Inqubo iya ukuhleleka kuka egcwele.

Futhi ekugcineni, ngelinye lamavesi abaluleke kunawo wonke, kodwa ngesikhathi esifanayo izindlela ezilula semininingwane ukucutshungulwa - ukuhlunga inketho. Njengoba kushiwo ngenhla, lisho iqembu yangaphakathi futhi kusekelwe kuyo kungenziwa exhunywe izinhlobo eziningana. Ingqikithi indlela - ukukhethwa, futhi amaningi ngesinye sezinqumo. Izenzo lwenziwa oda elandelayo: komncane kunabo kuyakhethwa kusuka nto yohlu, khona-ke kufanele ithunyelwe endaweni okukhipha futhi esikhundleni inani layo ngu ukwedlula abanye. Kulandzelana kwalokucuketfwe lokuhleliwe izenzo iyaphindwa kuze ukukhethwa ephelele yonke idatha ohlwini.

Kuyacaca ukuthi ukuqaliswa algorithm zidinga ukubonakala zonke izakhi kanye, ngaphezu, insimu idatha okukhipha. Futhi lapha kukhona indlela yemvelo kakhulu - ukuhlunga okukhethayo elula, ukuthi lephula uhlu ku eziningana. Lapho kufanele ukhethe isici encane kunazo zonke elifanayo bese ushintshashintsha izindawo naye kuqala. Ngokuhamba lemisuka ukuthi baphinde ekwenzeni manipulations enjalo nekuhambisana.
