if导航系统2.0源码（导航ifs）
本文目录一览：
求最短路径的动态规划实现源代码，用C语言在tc2.0中能运行。
希望下面的能对你有所帮助.
我只给出向前处理的代码,
向后处理的你自己改吧,
不然就变成我帮你做作业了.
你可以从递归式"tmp
=
w+GetBestpathF(g,
i,
s,
n,
path);"中看出递推式.
函数名:
GetBestpathF()
参数说明:
g
-Graph
,多段图对象
t
-int,源点
s
-int,汇点
n
-int,总结点个数
path
-Vertex
*,
记录中间路径
函数说明:
后向处理.
函数返回多段图最短路径,
并记录出最短路径的中间结点.
float
GetBestpathF(Graph
g,
int
t,
int
s,
int
n,
Vertex
*path)
{
float
tmp
=
MaxValue;
float
cost
=
MaxValue;
if
(t==s)
return
0;
else{
for
(int
i=0;
ig.NumOfVertices();
i++){
float
w
=
g.GetWeight(t,
i);
if
(w!=0
w!=MaxValue){
//t点到i点的路径存在
tmp
=
w+GetBestpathF(g,
i,
s,
n,
path);
//t的下一个点i到汇点s的最优路径值
if
(tmpcost){
cost
=
tmp;
AddtoPath(t,
i,
path);
}
}
}
}
return
cost;
}
sony网站导航的源码怎么做啊？
FLASH的效果。
用Javascript也可以实现。
我这里有个HTML的。没有用JS
