Stop for a second and look out your window. You’ll likely see a tree somewhere outside. Do you know its species? How often should it be watered? Is it healthy? Pietro Perona imagines a world where you ...

This paper first discusses the storage structure of trees, selects a convenient storage method for solving the nullity of trees, and then applies the relationship between the maximum matching number ...

If you haven't yet bought a Christmas tree yet, you may have left it a bit late. But don't despair: there's still time to print one. And a new 3D printer algorithm that claims to provide ...

Given a connected undirected graph ( G = (V, E) ), the Maximum Leaf Spanning Tree (MLST) problem aims to find a spanning tree ( T ) of ( G ) such that the number of leaves (vertices with degree 1 in ( ...

Abstract: Based on the limitations of the Tree Seed Algorithm (TSA), such as its proneness to getting trapped in local optima and its relatively slow convergence speed, this study proposes an improved ...

This C++ code implements a Graph data structure and includes various graph algorithms such as Dijkstra's shortest path algorithm and Kruskal's Minimum Spanning Tree (MST) algorithm. It is divided into ...

We develop a modified willow tree algorithm for option pricing. Our numerical results show that the modified algorithm approximates the true prices more quickly and precisely than the binomial tree ...
