Array of unit squares representing cells. One unit is in contact with the neighboring 8 units. l is the length of a unit, which is altered in each cell type. θ 1 (π/3) and θ 2 (π/6) are the angles which face to the side and the diagonal position of units, respectively. The influence probabilities from the neighboring units are 1/12 at a diagonal position (P inf×) or 2/12 at a side position (P inf+), which is determined by the angle
