Feb 8, 2023 · The triangle problem is a classic example of using boundary value analysis to test a software program. The problem involves determining if three values, representing the lengths of the sides of a triangle, form a valid triangle.

In the first lecture of the course, we will see how the seemingly sim-ple problem of counting the number of triangles in a graph gives rise to interesting algorithmic ideas, and some unexpected connections. Given an undirected graph G = (V, E), the triangle counting prob-lem asks for the number of triangles in this graph.

Given a graph G = (V; E), for every v 2 V , how many triangles in G include vertex v? The algorithms we'll discuss e ectively solve both of these problems at the same time.

vary depending on the problem: for example, an O˜(n2.9) algorithm for negative triangle implies an O˜(n2.96) algorithm for APSP. However, our runtime equivalences hold with respect to polylogarithmic improvements.

Oct 5, 2021 · Czumaj and Lingas proved that the min-node-weight triangle problem can be solved in n!+o(1) time. We will present their algorithm here.

We present two new quantum algorithms that either find a triangle (a copy of K3) in an undirected graph G on n nodes, or reject if G is triangle free. The first algorithm uses combinatorial ideas with

Problem 1. Given a graph G = (V;E), nd if G has a triangle. If G is given as an adjacency list, we can solve problem 1 in ( mn) using the following trivial approach. for every e = (u;v) 2E Check if the adjacency lists of u and v have a common element w. If such a w exists, output fu;v;wg. Output \No triangle Found"

Triangle - Given a triangle array, return the minimum path sum from top to bottom. For each step, you may move to an adjacent number of the row below. More formally, if you are on index i on the current row, you may move to either index i or index i + 1 on the next row.

Oct 21, 2003 · We present two new quantum algorithms that either find a triangle (a copy of K3) in an undirected graph G on n nodes, or reject if G is triangle free. The first algorithm uses combinatorial ideas with Grover Search and makes O~(n10/7) queries.

An alternative to solving both problems is the triangle algorithm [2], a geometrically inspired algorithm, initially described for the convex hull membership problem [3], a fundamental problem in linear programming.
