PROPHET通過節點間的曆史相遇資訊來估計傳輸機率。它使用一個稱為傳輸預測值Pa,b的參數作為路由度量，表示將訊息從節點a傳輸到上的節點b的傳輸機率。假設節點a要將訊息m傳輸到目的節點d，若節點a與節點b相遇，僅當Pb,d≥Pa,d時，a才將訊息轉寄給節點b。Pa,b的計算包括三個部分。當兩個節點相遇時，彼此都更新各自的傳輸預測值：P(a,b) = P(a,b)old + (1-P(a,b)old) x

JScript中WScipt.Shell對象有三個關於註冊表操作的函數,即RegRead,RegWrite和RegDelete.(以下內容摘自MSDN,另外我加上了一些樣本和注釋)1,RegRead Returns the value of a key or value-name from the registry. object.RegRead(strName) Arguments object

輸入：所輸入的是一個檔案，至多包含n個正整數，每個正整數都要小於n，這是 n = 10^7。如果輸入時某個整數出現了兩次，就會產生一個致命的錯誤。這些整數與其他任何資料都不關聯。輸出：以增序形式輸出的經過排序的整數列表。基本思想：使用一個具有一千萬位的字串表示該檔案，在該字串中，若且唯若整數i在該檔案中時，第i個位才開啟（設為1）。解決該問題的過程可以分為三個自然階段。第一個階段關閉所有的位，將集合初始化為空白集。第二個階段讀取檔案中的每個整數，並開啟相應的位，建立該集合。第三個階段檢查每個位，
