Review
BMRSs are
- logical descriptions of maps
- series of definitions of the form \[ [\mathrm{F}]_o(x) = \begin{array}[t]{l} \mathtt{if}~\mathrm{(condition 1)}(x)~\mathtt{then}~{\top/\bot}~\mathtt{else}\\ \mathtt{if}~\mathrm{(condition 2)}(x)~\mathtt{then}~{\top/\bot}~\mathtt{else}\\ \vdots\\ [\mathrm{F}]_i(x) \end{array} \]
- computationally restrictive (Bhaskar et al., 2020; [pdf;pub link]).
