Google Maps API V3 - 如何通過任意路點獲得最佳往返路線

Question

關於Google Maps V3 API路線點有許多問題，但沒有解決如何從一組任意路點獲得最佳往返路線的問題。基本上，衡量點的順序應該由最佳路徑決定，而不一定由饋入系統的順序決定。有人知道這是否可能嗎？

Answer 1

V3 API中有一個「優化」選項。你試過了嗎？

optimizeWaypoints

從 https://developers.google.com/maps/documentation/javascript/reference

If set to true, the DirectionService will attempt to re-order the supplied 
intermediate waypoints to minimize overall cost of the route. If waypoints 
are optimized, inspect DirectionsRoute.waypoint_order in the response to 
determine the new ordering. 

optimizeWaypoints (optional) specifies that the route using the supplied 
waypoints may be optimized to provide the shortest possible route.
