Design Dijkstra variant for
top-k shortest paths
Analyze the design dijkstra variant for top-k shortest paths.
Examples
Example 1
Input:
"test_input_1"
Output:
"output_1"
Example 2
Input:
"test_input_2"
Output:
"output_2"
Hints
Hint 1
Consider how Dijkstra's algorithm can be modified to keep track of multiple shortest paths instead of just the single shortest path.
Hint 2
Explore the use of a priority queue to manage the top-k paths efficiently, ensuring that you always expand the most promising candidates first.
Hint 3
Investigate the concept of "path dominance" and how it can be leveraged to prune suboptimal paths early in the search process.
