Rejection domain \(\Gamma (\boldsymbol {\tilde s})\), e.g. point x in the rejection domain, and y in the acceptance domain.(A) One separating boundary that consists of d lines with each emitting from \(\boldsymbol {\tilde s}\) to infinity in parallel to one axis of the orthant. (B) Choice (c) defines a hyperplane that passes \(\boldsymbol {\tilde s}\) and uses its vector direction as the normal direction. While choice (b) takes the normal direction by the primary diagonal direction of the orthant.
