The matte developed from growth of patches and its greatest height occurred in more continuously occupied cells of the grid.
To ensure the sufficient accuracy of the solution, the workspace in our case is divided into 1,028,519 cells of the grid (which corresponds to 1,473,273 nodes of a hexagonal grid).
The bars were arranged within a subset of the cells of the grid, which were 1 deg apart, center-to-center; and the bar positions were each displaced by a random vertical and horizontal factor of+/− 0.2 deg to reduce rectilinear configuration effects (e.g., collinearity).
The term N i, j) denotes the set of neighboring grid cells of the grid cell with the coordinates i and j and the term n i, j) represents the number of these neighboring grid cells (i.e., n i, j) = | N i, j)|).
As part of a different collaboration, one of us (VB) has been investigating the consequences of this variability for spatial coverage – it seems to produce significant differences in the relative phase of grid cells between unit cells of the grid lattice.
The locations at which the outer boundary of a given shape crossed the cells of the grid provided an address table of boundary locations, and this table was subsequently sampled to specify the positions on a 64 × 64 LED display board that were activated to display each shape pattern.
This number of cells for the grid size described above represents the average density of cells observed in literature [ 4].
Yet, navigation in off-road environments highly benefits from both approaches: perception data effectively condensed in regular grids, and global references for every cell of the grid.
Each cell of the grid represents one server, and its color depends on the health of that particular server.
We simulate users only in the central cell of the grid, whereas the remaining cells are a source of interference.
