Cryptocurrency projects are embracing partnerships with powerful tie-ups within the market. Some examples are Avalanche (AVAX), and its latest collaboration with Amazon Web services (AWS), Cosmos (ATOM) with Dymension, etc. In this article, we will discuss these projects in detail. You’ll also learn about the world’s first decentralized trading platform for traditional investments, TMS Network (TMSN). Avalanche (AVAX) Joins Amazon Web Services (AWS) For A New Project Avalanche (AVAX) is planning to offer a new crypto…

There are a few instances when duplicate nodes can occur in the heap when using Dijkstra’s algorithm:Case 1: When multiple edges have the same weight between two vertices, a duplicate node can be added to the heap when updating the distance from the starting vertex to the neighboring vertex. For example, consider the following graph:       A     /  \  B    C  /     /  \D   E   FEdge weights between these vertices are:AB = 2, AC = 3, BD = 1, CE = 2, CF = 2, DE = 2If we start at vertex A and use Dijkstra’s algorithm to find…

Given a graph with n nodes and m edges, each edges = and d as the maximum distance to reach the neighbor nodes, the task is to find the total number of nodes with maximum reachable neighbors.Input: n = 4, edges = , , , ], d = 4Example 1Output: 2Explanation: node 0 ->  node 1 ->  node 2 ->  node 3 ->  These are the nodes that are reachable with a maximum distance of d. Thereby out of these node1 and node2 can reach maximum neighbors (3 neighbors). So the answer is node1 and node2, i.e. 2. As we need to return…

All-Pair Message Passing with O(N)Image: Unsplash.Recently, building Transformer models for handling graph-structured data has aroused wide interests in the machine learning research community. One critical challenge stems from the quadratic complexity of global attention that hinders Transformers for scaling to large graphs. This blog will briefly introduce a recent work on NeurIPS22:NodeFormer: A Scalable Graph Structure Learning Transformer for Node Classification with its public implementation available.This work…

You can choose any node from the tree and add 1 to all nodes in the path from the root of the tree to that particular node. The task is to find the minimum number of operations to make all the values of the…

Trees are nonlinear data structures that organize data hierarchically and in a recursive manner. It is a method of organizing and storing data in the computer in a way that makes it more effective to use. Nodes in the graph are connected via edges. It has different types of nodes which are called parent node, child node, leaf node, etc.What is a root node?A node that is the first or topmost node in a tree is called a root node. In every tree, there is always one root node, which is the only node that has never previously…
