解决最短路径算法的D算法，是一个解决从点到点之间最短路径的问题，看下面这张图：
var INFINITE = 65535;
var NODE_NUMBER = 6;
var weight =
[
[0, 7, 9, INFINITE, INFINITE, 14],
[7, 0, 10, 15, INFINITE, INFINITE],
[9, 10, 0, 11, INFINITE, 2],
[INFINITE, 15, 11, INFINITE, 6, INFINITE],
[INFINITE, INFINITE, INFINITE, 6, 0, 9],
[14, INFINITE, 2, INFINITE, 9, 0]
]
var dis = [0, 7, 9, INFINITE, INFINITE, 14];
var s = [1, 0, 0, 0, 0, 0];
for (i = 1; i < NODE_NUMBER; i++) {
var minWeight = INFINITE;
var v = 0;
for (var j1 = 0; j1 <= NODE_NUMBER; j1++) {
if (![s[j1]] && dis[j1] < minWeight) {
v = j1;
minWeight = dis[j1];
}
}
s[v] = 1;
for (var j2 = 0; j2 < NODE_NUMBER; j2++) {
if (!(s[j2]) && weight[v][j2] < INFINITE) {
if ((dis[v] + weight[v][j2] < dis[j2])) {
dis[j2] = dis[v] + weight[v][j2];
}
}
}
}
console.log(dis);
