Dally's theorem

Dally's theorem provides a way to calculate the shortest path or minimal cost to reach a certain point in a network, such as a transportation or communication system. It states that the optimal solution can be found by examining the most promising partial solutions and ensuring no other options offer a better route. Think of it as a method to efficiently identify the best way to connect nodes in a network by systematically considering and ruling out less efficient paths, ensuring that the overall route chosen is optimal and cost-effective.
