I ka olelo hooholo iaaiey. puni Robin

Ke kū hoʻokahi o ka iaaiey nā papaha mohai aku ma ke kālā no kamepiula nenoai o ka nanea a me ka loaʻa nui o ka pau pae o pāʻoihana no nā hana likeʻole. mea, noonoo koke i ka loa eiiieaena nīnūnē a mai i koi hou lilo i nā manawa a me ka 'imi naʻauao ho'āʻo pono o ka programmer. Oʻoi loa-auoiauo kōkua hana me ka kūikawā me kaʻaluna ma muli o ka mea hoʻohana i mea maʻa iā mākou a hiki i ka papa o ka kamepiula 'epekema o ke kula kiʻekiʻe.

Noho ana i ka manaʻo o kekahi o kona manaʻo i loko o ke Kanawai, i ka programmer makemake i e lawe mai i ka kiʻikuhi ano o ka pāʻoihana holomua. Ua Ua lōʻihi, ua manao iho la oia i na rula a me nā kaʻina hana no ka unuhi aku la ia i algorithms. Ma ka moʻokalaleo algorithm Ho'ākāka 'ana i kūlike loa a me ka maopopo kuhikuhi e hoʻokō pololei kekahi kaʻina o nā hana. E like me ka hopena o ko lākou hoʻokō 'ana i ka pahu hopu e piʻi like ai mākou e hele ma ka pāʻoihana o ka pilikia.

Kona inoa, i ka manawa "algorithm" Ua kapaʻia ma hope o ka Uzbek thinker Al-Khwarizmi. Kana hana "ka makemakika hoonoho" lilo i ke kumu o na rula o ka makemakika ana ma luna loa, a me na rula lakou i kapa like algorithms. Me ka hou, subtraction, mahele a me ka multiplication o ka honua mōʻaukala hoomaka iaaiey.

ʻO nā papa o kekahi aoao, e hoʻoponopono i like hana hoʻokuʻu akula a Robin. He mea e like me ka hele i loko o ka poai nei, e hoʻokō i kekahi pahuhopu. Iaaiey i ka puni Robin i kekahi pilikia, ia mea i ka hewa o ko lākou ke kaha kiʻiʻana a typo kamepiula ke "ahau," 'o ia hoʻi, e hele i ka hana i ka mana loa helu o ka manawa i ka ia hana.

E like me ka laekahi 'ano o ka cyclic algorithm - o ka mea o kekahi mau hana i i hai hou ma hoʻololi i ka mua ikepili. E iho, keia hana ua lawe mai kekahi mau pilikia ole. Cyclic algorithm mea he laina pu ana o ka algorithm a me ka algorithm manamana ai.

I loko nō o ka noho nanea oe o ka manaʻo a me ka kekahi uniformity pilikia no kēia 'ano o ka algorithm ua wehewehe aku ma ke alo o kekahi o ko lākou mau? Ueo. Kaluakauwa Robin ua hoʻohana 'ia no ka ana i loko o ka hana pono i keʻano ekolu o ka pōʻaiapuni. Ma ko lakou mau inoa hiki ke 'ike ma luna o kā lākou mau' ano a me ke ano o ka hana.

Kalapona me ka precondition komo ai makau 'ia Kaha kūlana no ka hooko ana i ka algorithm mua o ka papa inoa o nā hana (ua kālaiʻia me ka laina algorithm). Me ka postcondition kalapona ÿokoÿa mai ka mua kekahi i loko o ia ano, kulana kupono paha ma hope o ka hōʻike laina ke keʻena. No ka mea pōʻaiapuni aiao wehewehe aku ma ke alo o ka kekahi huahelu, māhuahua a emi me ka hoʻokō 'ana o ka papa inoa o nā hana. Kaluakauwa Robin me ka mika, i kekahi manawa haawiia keia i like me ka ano o ka pōʻaiapuni.

I loko nō o ka pono io o ka manaʻo o kēia 'ano o ka algorithm, elua emi huikau wale nō o kēlā kēia iaaiey' ōlelo i kona mau ho'ākāka 'ia paha o nā kauoha e i hoʻouluulu pōʻaiapuni. Ma keia hihia, e hiki ke hana i kekahi i loko o ke kino o ka polokalamu, mai kekahi i mau pōʻaiapuni, ke kaumaha ma muli o ka 'ano o ka pilikia i ka wehe pilikia.

Lakou iho a Robin loaa he nui hohola i loko o ka iaaiey kaʻina. Ma waho aʻeo i kekahi papahana e hana kekahi hana, eia ka ipu pōʻaiapuni. Kā lākou hana mea e ho okumu ana i mō'ī.

Kalapona iho hiki ho i elua, he pono ole nä hopuna. No ka laʻana, ka mea i mua o ka poepoe Robin ke kēia hoike.

- hamo i ka hainaka;

- ina heʻino hainaka, alaila, e hele i ka hoʻomaka.

Oe ke manaʻo o ka hailonaʻana no ia examples. Nui hou aku nā pōʻaiapuni hoike mai ai ia lakou iho ma ka hana o nā kiʻi mau hana, a hiki i ka hanaia'na o ke raster ma luna o ka pale o ka aie kalapona papahana. Huihui ikehu lā, Logical pilikia, kaumaha, a laila, hoʻokipa polokalamu a hiki ole ke hana me ka pono o cyclic algorithms.
