Excluding a planar graph from GF(q)-representable matroids
Abstract. We prove that a binary matroid with huge branchwidth contains the cycle matroid of a large grid as a minor. This implies that an infinite antichain of binary matroids ca...

Application-level simulation modelling of large grids
The simulation of large grids requires the generation of grid instances and an approximation of grid components’ behaviour. To generate grid instances, this paper outlines a set...
