Let G be a directed graph such that every edge e of G is associated with a positive integer, called the index of e. Then G is called a network graph if, at every vertex v of G, the sum of the indices ...

* Why do you want to base this on Dijkstra's algorithm, which is designed to find a single shortest-path? Surely there are better options for your base implementation. A quick Google search suggests a ...

Bitcoin, created by an anonymous entity known as Satoshi Nakamoto, utilizes a blockchain, a distributed and immutable ledger that records all transactions in a linear fashion. Each block in the chain ...

Well, if I remember my graph theory well enough, if A is the adjacency matrix of the graph, each entry of A^n is the number of ways to get between the corresponding nodes in n steps or less. So, to do ...

In this paper we consider specific directed graphs called "ladders". The vertices of the graph are randomly colored by green or red. Deleting the edges with at least one red endpoint one gets a random ...

The presentation will introduce the DACM (Dimensional Analysis Conceptual Modeling) approach as a way to represent an engineering problem in the form of oriented colored graphs. The foundations of the ...
