In my algorithms class at University, there were many subjects learned on paper. Some were more easily translated to code (i.e Knapsack, Longest Increasing Subsequence), but others, mainly graph based ...

Nowadays, Knowledge Graphs (KGs) are important and developing in different areas. However, there is a lack of genuinely interoperable datasets representing mathematics that allow for information ...

This paper studies the mathematical morphology operators acting on a lattice of all intuitionistic fuzzy sub graphs of an intuitionistic fuzzy graph (IFG). p n -adjacency of vertices and edges are ...

In the realm of modern computational sciences and engineering, the complexity of problem-solving often exceeds the capacities of traditional algorithms. Graph partitioning, a fundamental challenge in ...

Abstract: Tactile graphics are images that use raised surface so that a visually impaired person can feel them. Tactile graphics are necessary to visually impaired students when they study mathematics ...

Graph Grabber is a tool that enables users to extract data points from a graph image. This is particularly useful when it is necessary to retrieve data from a published graph or graph image file ...
