Our current interpretation is that each bin in a 2D delay interaction inherits a flow rate from the horizontal 'host' population, and a flow rate from the vertical 'pest' population.
Combined, these rates create diagonal diffusion in the system.
Questions
Is the diagonal diffusion a result of the model as described, or is the model an approximation to diagonal diffusion? That is, could each bin have an equational component which sits between the 'host' and 'pest' axes?
The implemented 2D model depends on the order in which the equations are executed, in the sense that travelling from bin (i, j) to (i+1, j+1) via (i+1, j) is different to travelling via (i, j+1). These issues can be resolved with solutions listed in discrete modelling: eg. double buffering or continuous time modelling.
Mortality rates are implemented outside of the ODE structure, but we note these can have an (i, j)-dependence in the equations given in papers.
