Detailed Description
template<typename GeneType>
class galib::BestNeighborSelection< GeneType >
class galib::BestNeighborSelection< GeneType >
Selects the fittest direct neighbour of a cell in a cellular grid.
The neighbourhood is the Von Neumann neighbourhood: up, down, left, and right. Grid boundaries wrap around, so border cells still have four neighbours.
- Template Parameters
-
GeneType Numeric type of each gene.

Returns the best direct neighbour of the specified cell.
- Parameters
-
population Population interpreted as a 2D grid in row-major order. row Row of the current cell. col Column of the current cell. rows Total number of grid rows. Must be non-zero. cols Total number of grid columns. Must be non-zero.
- Returns
- Const reference to the neighbouring individual with the lowest fitness.
- Exceptions
-
std::invalid_argument if rowsorcolsis zero.
