Mathematical description

Given a grid with

m

rows and

n

columns, a function

f(m,n)

\displaystyle  = \begin
\text & \text\ m \equiv n \pmod 2 \, , \\
\text & \text\ m \not\equiv n \pmod 2\\
\end

or, alternatively,

\displaystyle  = \begin
\text & \text\ m + n \text, \\
\text & \text\ m + n \text \\
\end

The element

(m,n)=(0,0)

is black and represents the lower left corner of the board.
