Graph theory: Solution to '3 utilities problem' could lead to better computers Date: August 17, 2020 Source: University of Copenhagen Summary: Researchers thought that they were five years away ...

Bisection problems, in particular, focus on the nearly equal division of a graph and are closely linked to studies in spectral graph theory and approximation algorithms.

Basic concepts of Graph Theory are discussed which are relevant to solving problems of locating economic activities within a service or manufacturing facility. The location problem is formulated in ...

As we approach the 300th year of graph theory, we can reflect on what this field has offered humanity and where it is going next. Simply put, graph theory studies connections between objects.

One way to detect this problem is by using time series data to calculate demographic synchrony within mega-patches. We present a framework for identifying subpopulations in mega-patches using a ...

KALAMAZOO, Mich.—Western Michigan University's international reputation on the topic of graph theory is on display in a new book published recently by Princeton University Press. Graph theory, a ...

Teaching graph theory This August, I will teach a course entitled “Graph Theory: Problems, Proofs and Conjectures,” specifically geared toward incoming first-year students.

It would be interesting to find a vertex transitive graph whose matching polynomial has a nonsimple root. Such a graph would not have a hamiltonian path (see [1,2]) and would disprove a conjecture of ...

University of California (UC) San Diego mathematicians Jacques Verstraete and Sam Mattheus have solved a puzzling Ramsey theory problem that's had little progress since the great Paul Erdös made ...
