Size-constrained graph partitioning polytope. Part II: Non-trivial facets

We consider the problem of clustering a set of items into subsets whose sizes are bounded from above and below. We formulate the problem as a graph partitioning problem and propose an integer programming model for solving it. This formulation generalizes several well-known graph partitioning problems from the literature like the clique partitioning problem, the equi-partition problem and the k-...

On well-covered triangulations: Part II

A graph G is said to be well-covered if every maximal independent set of vertices has the same cardinality. A planar (simple) graph in which each face is a triangle is called a triangulation. It was proved in an earlier paper [A. Finbow, B. Hartnell, R. Nowakowski, M. Plummer, On well-covered triangulations: Part I, Discrete Appl. Math., 132, 2004, 97–108] that there are no 5-connected planar w...

Investigating the effect of the removing well-known periods from TEC time series data in identifying seismo-ionospheric anomaly

Iran is situated on one of the two largest seismic belt of the world which is called Alpa. The occurrence of damaging earthquakes all around the country causes a lot of pecuniary losses and casualties. The prediction of this phenomenon can have a profound impact on reducing the risks which are posed by it. Among the earthquake predictors, which are of interest to many scholars today, we can men...
