回溯（b a c k t r a c k i n g）是一種系統地搜索問題解答的方法。為了實現回溯，首先需要為問題定義一個解空間（ solution space），這個空間必須至少包含問題的一個解（可能是最優的）。在迷宮老鼠問題中，我們可以定義一個包含從入口到出口的所有路徑的解空間；在具有n 個對象的0 / 1背包問題中（見1 . 4節和2 . 2節），解空間的一個合理選擇是2n 個長度為n 的0 / 1向量的集合，這個集合表示了將0或1分配給x的所有可能方法。當n= 3時，解空間為{ ( 0 , 0 , 0 )，( 0 , 1 , 0 )，( 0 , 0 , 1 )，( 1 , 0 , 0 )，( 0 , 1 , 1 )，( 1 , 0 , 1 )，( 1 , 1 , 0 )，( 1 , 1 , 1 ) }。

In this paper, we describe the development of a mobile butterfly-watching learning (BWL) system to realize outdoor independent learning for mobile learners. The mobile butterfly-watching learning system was designed in a wireless mobile ad-hoc learning environment. This is first result to provide a cognitive tool with supporting the independent learning by applying PDA with wireless communication technology to extend learning outside of the classroom. Independent learning consists of self-selection, self-determination, self-modification, and self-checking.

Our approach to understanding mobile learning begins by describing a dialectical approach to the development and presentation of a task model using the sociocognitive engineering design method. This analysis synthesises relevant theoretical approaches. We then examine two field studies which feed into the development of the task model.

％The phase locked loop(PLL),adjusts the phase of a local oscillator ％w.r.t the incoming modulated signal.In this way,the phase of the ％incoming signal is locked and the signal is demodulated.This scheme ％is used in PM and FM as well. ％We will implement it by using a closed loop system.Control systems ％techniques are applied here.
