Generic Dijkstra is a novel algorithm for finding the optimal shortest path in both wavelength-division multiplexed networks (WDM) and elastic optical networks (EON), claimed to outperform known algorithms cons
For example, if we say that an algorithm has a time complexity of O(n), it means that the algorithm’s execution time increases linearly with the size of the input. If the input size doubles, the time it takes to run the algorithm will roughly double as well. If an algorithm is O(...

Algorithm 给定一个输入图,算法首先计算它的线图(对于要选择边的问题),节点或边的权重作为输入到GNN的特征。算法首先使用GAT编码器创建输入的dense representation。然后算法循环迭代n次,使用解码器选择要添加的原始节点或边作为动作。损失是使用奖励的策略梯度计算的。
Their main difference is, that Johnson’s algorithm can additionally deal with negative weights by adjusting weights before searching paths with Dijkstra’s algorithm. Since complex network theory forbids negative weights, they have the same complexity (and normally the same practical runtime). Because...
We used Dijkstra's algorithm13 to find the shortest paths (parent-vertex lists) from every non-root marker to the root. We detected in these lists the vertexes where two or more paths merge. These vertexes were treated as the branching points of the reconstructed neuron tree. Subsequently,...
Trees are the first class of graphs that a polynomial-time algorithm for the longest path problem has been found for (i.e. finding the diameter of an unweighted tree). Originally, this algorithm was proposed by Dijkstra around 1960 but Bulterman et al. [2] provided a proof for it, and...
Next, in Section 3 we introduce the relevant graph approach for computing the shortest path in transfer graph and two implementations based on Dijkstra and ACO, concluding with the benefits and drawbacks of both strategies. Then, we present the new algorithm for TMTP in Section 4 and we prove...
