Iyini inkolelo-mbono yegrafu?
Context:Kuzibalo, i-graph theory yisifundo sama-graph, okuyizakhiwo zezibalo ezisetshenziselwa ukwakha ubudlelwano phakathi kwezinto. Igrafu kulokhu yakhiwa ama-vertices (abizwa nangokuthi ama-node noma amaphuzu) axhunywe ngemiphetho (ebizwa nangokuthi izixhumanisi noma imigqa). Kwenziwa umehluko phakathi kwamagrafu angaqondisiwe, lapho imiphetho ixhumanisa khona ama-vertices amabili ngokulingana, kanye namagrafu aqondisiwe, lapho imiphetho ixhumanisa khona ama-vertices amabili ngokungafani. Amagrafu angenye yezinto eziyinhloko ezifundwayo ezifundweni zezibalo ezihlukene.
Umbono wegrafu uwukufundwa kwamagrafu, okuyizakhiwo zezibalo ezisetshenziselwa ukwakha ubudlelwano obubili phakathi kwezinto.
