Given a weighted directed acyclic graph (DAG) and a source vertex, find the cost of the longest path from the source vertex to all other vertices present in the graph. If the vertex can’t be reached from the given source vertex, print its distance as infinity. For example, consider the...
graphconstraintlocal searchschedulingModeling and programming tools for neighborhood search often support invariants, i.e., data structures specified declaratively and automatically maintained incrementally under changes. This paper considers invariants for longest paths in directed acyclic graphs, a fundamental...

longest increasing subsequence. Therefore, longest increasing subsequence algorithms can be used to solve the clique problem in permutation graphs.[3]The longest increasing subsequence problem can also be related to finding the longest path in a directed acyclic graph derived from the input sequence.
This means that there are no cycles in the network, you can never find a path from a node that returns to that node. Thus a citation network is an example of a Directed Acyclic Graph (DAG). Mathematically, DAGs have some distinctive properties and one of them is that for any pair of...
We know that the longest path problem for general case belongs to the NP-hard category, so there is no known polynomial time solution for it. However, for a special case which is directed acyclic graph, we can solve this problem in linear time. ...

Optimized Longest Path is NP Complete - The Upgraded Longest Way issue is a computationally difficult undertaking, ordered as NP-complete. In this issue, given a diagram with weighted edges, the goal is to find the longest way from a predetermined beginn

This paper proposes an algorithm called the Maximum Length Recalculation Algorithm (MLRA) to update the length of the longest path to affected nodes in a perturbed Directed Acyclic Graphs (DAG) where multiple edges are simultaneously deleted and added. MLRA can find all these lengths through a ...
