  • 摘要: 不確定因素在現(xiàn)實(shí)世界中普遍存在,因此研究不確定網(wǎng)絡(luò)條件可信近鄰查詢(xún)具有重要意義。該文給出一種新的解決方法。將不確定網(wǎng)絡(luò)建模為不確定賦權(quán)圖,定義不確定圖的樣本圖,樣本圖指數(shù),基礎(chǔ)網(wǎng)絡(luò),可達(dá)路徑長(zhǎng)度及可達(dá)路徑期望長(zhǎng)度,并給出基于不確定理論的高效不確定圖條件可信近鄰查詢(xún)算法。將不確定網(wǎng)絡(luò)上的近鄰查詢(xún)等價(jià)地轉(zhuǎn)化為基礎(chǔ)網(wǎng)絡(luò)上的近臨查詢(xún)問(wèn)題。理論分析和實(shí)驗(yàn)結(jié)果表明所提可信近鄰查詢(xún)算法能夠從非確定角度解決不確定網(wǎng)絡(luò)環(huán)境下的近鄰查詢(xún)問(wèn)題。
