The baseline solution for your problem is to realize that your states are now pairs (the graph node where you are, the amount of energy you have already spent) and then you can use Dijkstra to compute, for each state, the shortest time in …

WebNov 8, 2024 · We can find it using Dijkstra’s algorithm, Uniform-Cost Search, and A*, among other algorithms. 3. Dijkstra’s Algorithm The input for Dijkstra’s Algorithm contains the graph , the source vertex , and the target node . is the set of vertices, is the set of edges, and is the cost of the edge . WebUniform-cost search is a searching algorithm used for traversing a weighted tree or graph. This algorithm comes into play when a different cost is available for each edge. The primary goal of the uniform-cost search is to find a path to the goal node which has the lowest cumulative cost.
