Yini i-Heuristic Algorithms?
Ama-algorithm e-heuristic ayizindlela zokuxazulula izinkinga ezisebenzisa imithetho noma izimiso ezijwayelekile ukuthola izixazululo ezilinganiselwe noma ezingafanele. Ngokungafani nama-algorithm aqondile, afuna ngokuphelele ikhambi elifanele, ama-heuristics anikeza izixazululo ezisheshayo eziseduze nekhambi elingcono kakhulu. Lawa ma-algorithms athembele ekucabangeni okulinganiselwe, ulwazi, kanye nokwahlulela ukuze aqondise inqubo yokusesha futhi afinyelele ikhambi elanelisayo ngesikhathi esifanele.
Ama-algorithms we-Heuristic asetshenziswa emikhakheni ehlukahlukene, njengobuhlakani bokwenziwa, ukwenziwa ngcono komzila, ukwakheka kwenethiwekhi, ukufunda ngomshini, nokunye okuningi. Lawa ma-algorithms afakazele ukuthi asebenza kahle ekuxazululeni izinkinga eziyinkimbinkimbi lapho ukuthola isixazululo esilungile kubiza ngokwezibalo noma kungenzeki nhlobo ngesikhathi esifanele.
I-Heuristic Algorithms in Practice
Zisetshenziswa ezimeni eziningi zomhlaba wangempela ukuxazulula izinkinga eziyinkimbinkimbi. Ngezansi sizohlola izibonelo ezithile eziphawulekayo:
Ukuthuthukisa Umzila ngama-Heuristic Algorithms
Ama-algorithms we-Heuristic asetshenziswa kakhulu ekwenzeni umzila, inkambu efuna ukuthola ukulandelana okungcono kakhulu kwamaphoyinti kumephu. Cabanga ukuthi ungumphathi wenkampani yezokuthutha futhi udinga ukuletha amaphakheji ezindaweni ezahlukene ngendlela ephumelelayo ngangokunokwenzeka. Yilapho ama-algorithms we-heuristic eqala ukudlala.
Enye yama-algorithms e-heuristic aziwa kakhulu okwenza ngcono umzila yi- Nearest Neighbor Algorithm .
