Initial condition for abm-aor simulation 1 is discussed in this note.
mpm
A matrix named as movement probability matrix (MPM) is used to define probable new position of agents, which has form as follow
$$\tag{1} {\rm MPM} = \left[ \begin{matrix} m_{11} & m_{12} & m_{13} \newline m_{21} & m_{22} & m_{23} \newline m_{31} & m_{32} & m_{33} \end{matrix} \right], $$
where directions represented by each matrix element are given in following table.
| Element | Direction | Compass Term |
|---|---|---|
| $m_{11}$ | Upper-left | Northwest (NW) |
| $m_{12}$ | Up | North (N) |
| $m_{13}$ | Upper-right | Northeast (NE) |
| $m_{21}$ | Left | West (W) |
| $m_{22}$ | Stay | (No movement) |
| $m_{23}$ | Right | East (E) |
| $m_{31}$ | Lower-left | Southwest (SW) |
| $m_{32}$ | Down | South (S) |
| $m_{33}$ | Lower-right | Southeast (SE) |
Or following
$$\tag{2} {\rm MPM} = \left[ \begin{matrix} \nwarrow & \uparrow & \nearrow \newline \leftarrow & \circ & \rightarrow \newline \swarrow & \downarrow & \searrow \end{matrix} \right] $$
is representation of MPM in more visual way.

notes
- There is a code for generating an input for the abm-aor simulation 2.
- Some bugs are found that MPM alone is not sufficient 3.
- Number of agents is 600.
