Given $d$ different experimental variables with $m_i$ choices per design variable $1 \\le i\\le d$, the goal is to select $k_i \\le m_i$ experiments per design variable. Previous work has related OED to the column subset selection problem by mapping the design variables to the columns of a matrix $\\mathbf{A}$. However, this approach is applicable only to the case $d=1$ in which the columns can be selected independently.
