Accelerated stochastic and hybrid methods for spatial simulations of reaction-diffusion systems

Analysis of the role of the number of molecules for the Gray-Scott equations solved with a 300 × 300 discretization with F = 0:04; 0:06; t = 1000. From left to right the number of molecules per unit of concentration is increased from 100; 1000; 1000; 5000; 10 000, continuum, respectively.
