Description: A*算法属于一种启发式搜索。它扩展结点的次序类似于广度优先搜索，但不同的是每生成一个子结点需要计算估价函数F，以估算起始结点到该结点的代价及它到达目标结点的代价的和；每当扩展结点时，总是在所有待扩展结点中选择具有最小F值的结点作为扩展对象，以便使搜索尽量沿最有希望的方向进行。 -A* algorithm is a heuristic search. It extended node in the order of priority similar to the breadth of search, but in every generation is a sub-node calculated valuation function F, to estimate initial node to the node, the price and it arrived at the target node, and the price; Whenever expansion node, the question has always extended to all nodes with the smallest choosing F value of the node as expansion targets, in order to search as far as possible along the most promising direction.

Description: 设计说明：1。数据结构和表示：程序用1、2、3、4分别表示将右、上、左、下的数字块移动到空格之中。采用典型的树+链表结构，每种局面产生一个BoardState类。出于避免走法顺序列表被过多复制的考虑，在树结构中保存局面的继承关系。每种新的局面产生后，引用估值函数产生f的值，再根据大小将其插入链表之中，以便实现“优先展开f值小的节点”。Solve()函数在成功解决问题之后保存一个走法序列供输出并返回零，而失败则返回失败处的节点层数。(具体的判断方法见后文)-Design Notes : 1.

A typical tree Chain structure, each have a situation BoardState category. For France order to avoid excessive copying the list was, in consideration of the tree structure to preserve the situation in relation to the succession. Each of the new situation after the election, have cited valuation function f value, in accordance with the size of its insertion Chain, in order to achieve the "priority start small f value of the node." Solve () function in the successful solution of the problem after a law to preserve sequence for output and return to zero. and failure to return to the failed node floors.

Description: This program demonstrates some function approximation capabilities of a Radial Basis Function Network.
The user supplies a set of training points which represent some "sample" points for some arbitrary curve. Next, the user specifies the number of equally spaced gaussian centers and the variance for the network. Using the training samples, the weights multiplying each of the gaussian basis functions arecalculated using the pseudo-inverse (yielding the minimum least-squares solution). The resulting network is then used to approximate the function between the given "sample" points. -This program demonstrates some function a pproximation capabilities of a Radial Basis Fu nction Network.

Description: A*算法是一个求最短路径的函数，为许多即时战略游戏所用刀（或许人家大型的即时战略游戏笔者算法更好，不管它）。它由两个函数组成，一个是评估函数，也就是确定人物移动的下一个位置必须离目标位置最近，评估函数评估的结果越精确，则寻径的速度越快；另一个就是寻径函数，也就根据评估的结果做出响应，然后从新位置继续评估下一个位置，若无路可走（四周都是障碍什么的），那么折回一个路径节点，尝试其他方向，这个算法有个缺点，随着游戏中人物增多，相应的处理节点就增多了，会影响处理速度，而且占用大量的内存。
有兴趣的朋友可以改成动态的寻径，就是当入口和出口位置都在变化的时候进行寻径，这个代码也只有200多行。
我的算法还不能算是最优的，因为评估函数只不过是简单的测试两点距离（这会带来误差），选择离出口最短的且非障碍物的方向，进行下一个路径节点的移动。-A* algorithm is a shortest path function, To many time strategy games as a knife (and perhaps others of immediate large-scale strategy game better writer algorithm, regardless of it). It consists of two components function, a function is to assess, is to determine the movement of people under one location to be away from the target location recently to assess the function of the assessment results more precise, Routing is the faster; Another is the routing function, also based on the results of the assessment to respond, then the new location to continue to assess a position where, if there is no way out (what are surrounded by the barrier), then retrace a path nodes, try other directions, this algorithm has a shortcoming, as the game figures increased, corresponding to the processing nod

Description: We present the technique of the ICA with Reference (ICA-R) to extract an interesting subset of independent sources from their linear
mixtures when some a priori information of the sources are available in the form of rough templates (references). The constrained
independent component analysis (cICA) is extended to incorporate the reference signals that carry some information of the sources as
additional constraints into the ICA contrast function. A neural algorithm is then proposed using a Newton-like approach to obtain an
optimal solution to the constrained optimization problem. Stability of the convergence and selection of parameters in the learning
algorithm are analyzed. Experiments with synthetic signals and real fMRI data demonstrate the efficacy and accuracy of the proposed
algorithm.
