Hi,<br>
<br>
I have two points A and B located in a large region. I need to find the<br>
optimal path between those 2 points. Without considering the whole area (all<br>
the edges), can I consider only a segment that will be required to find the<br>
optimal path. As all the edges (far away roads in other cities) will not be<br>
required to find the optimal path between two points in a city. If all are<br>
considered it will be a waste.<br>
<br>
What is the possible function to use and how to solve my issue?<br>
<br>
Hope to hear a reply soon. Thanks<br>
