# Shortest path problem

In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized. The problem of finding the shortest path between two intersections on a road map may be modeled as a special case of the shortest path problem in graphs, where the vertices correspond to intersections and the edges correspond to road segments, each weighted by the length of the segment.

From playlist Introduction to Algorithms The Shortest Distance Between A and B, with Two Reflections.

We present the solution to the shortest path problem between two given points with the constraint that the path needs to touch both x-axis and y-axis. A related problem is the Heron's shortest path problem. We give an visual animation of the problem and high level proof ideas. Both types
