A great significance of this article is that it changes the branch and bound algorithm and backtracking algorithm into application examples of the generic search algorithm of optimal problems advanced in this article 本文的一个重要意义是将回溯法和分支限界法这两个传统的算法策略转变为本文所提出的通用搜索算法的应用例子。
Enforced hill - climbing with backtracks can use the last searching results when enforced hill - climbing fails , so it is more fit for ff . helpful action ordering can save the time used by enforce hill - climbing through ordering the helpful actions 带有回溯的加强爬山算法在加强爬山算法失败时,通过回溯使规划器可以利用前一步的搜索结果来继续进行加强爬山搜索。
And would not bother parsing " color red . " perl 6 grammars have commit directives that specify that the current word , alternative , grammar rule , or everything up to the match operator is not to be backtracked after it matches Perl 6语法中包含一些提交指令，它们可以指定当前的单词、选择、语法规则或者一切内容，这取决于匹配操作符找到匹配的对象之后是否将被回溯。
The solution programs can employ several methods , but the most common is backtracking , a systematic form of trial and error in which partial solutions are proposed and then modified slightly as soon as they are proved wrong 有好几种方法可以用来写解题程式，其中最常用的是回溯演算法，这是一种有系统地尝试错误的方法：先提供部份解答，在发现错误时，再回头略做修正。
In order to handle the subgraph isomorphism problem , the concept of individuals with state backtracking was proposed , where the state information of some potential individuals produced during the evolution were preserved , which contributed to the design of genetic operators 针对图数据挖掘中经常遇到的子图同构问题，提出了带状态回溯个体的概念，从而使遗传算子的设计更为合理。
Searching of the state space is always being one of the usual ways for solving the optimal problems . the traditional ways of finding solutions only have backtracking , branch - and - bound and implicit graphs search as their theoretical introduction 状态空间搜索是解决优化问题的常用方法之一，传统的状态空间搜索求解技术有回溯法和分支限界法以及隐式图搜索这些算法策略作为理论指导。
The test vector set of the circuit can be obtained through constructing a test bdd . compared with the traditional algorithms , this method avoids enormous backtracking process . the second application is the network reliability based on bdd Bdd应用于数字电路的固定型故障检测，建立的故障节点的检测bdd可以比较方便地得出电路故障的测试矢量，相比传统的测试算法，避免了庞大的反向回溯过程。
Because of inablity of the handling dead end state , ff does not perform ideally in some planning problem domains such as gripper . in this paper , a new searching method enforced hill - climbing with backtracks is used , and a new method of helpful action ordering is presented 但是, ff规划算法所采用的搜索方法和规划图的使用上都存在很大不足,使得ff规划算法在某些规划问题域中,特别是含有死点状态的问题域中表现不够理想。
Setting up a qualified bibliographic - related database is critical to the normal operation of the whole tasks of libraries , the article tells about the difficulties and solution during the backtracking , and gives the details about the procedures , the principles it should follow and the problems we should pay attention to 本文论述了高职院校图书馆回溯建库工作中所面临的困境及解决的办法，并详细说明了回溯建库工作的工作程序、遵循的原则及应注意的问题。
