本程序是K条最短路算法测试程序,陈艳艳老师的K条路算法。程序求3条最短路,约束条件值可以设定,约束值越小,多路径共用路段越多。-Article K of the procedure is the shortest path algorithm to test procedures, Yan-Yan Chen K teacher path algorithm. Procedures for the three short-circuit, constraints can be set value, the smaller the value constraint, multi-path section of the more common.
