Discrete Ricci curvature formulations offer novel perspectives for characterizing geometric properties of weighted graphs. This work proposes continuous piecewise linear Ricci curvature flows and ...

In this paper, a new methodology for curve approximation is presented. The method is suitable for both self-intersected and non self-intersected curves, it combines elements from graph theory and from ...

Graph Pairs 1–6 deal with linear graphs, while Graph Pairs 7–9 include exponential and quadratic graphs. The linear graphs are generally easier for students to explore algebraically. If you wish to ...

A python implementation of the algorithm used to generate optimal piecewise linear approximations of convex functions proposed by Imamoto and Tang .The algorithm uses an iterative search to find the ...

So, although the piecewise-linear graph can be a pretty good approximation to real life, in real life no person would ever move like this. Instead, Charlie’s motion is probably more like this: ...

In this work, we propose a graph approach for stability of piecewise linear systems. A stability criterion is presented based on the attractivity of an invariant region. The approach is applied to ...
