Let $\mathbb F$ be a field of cardinality $q$ and let $0<k<n\leq q$ be unspecified integers. As seen in the lecture, we generate a $(n,k,d_{min})$ Reed-Solomon code with the following mapping: $$\mathbb F^k
ightarrow \mathbb F^n ~~,~~ \vec u \mapsto \vec c =(P_{\vec u}(a_1),P_{\vec u}(a_2),\ldots,P_{\vec u}(a_n))$$ for $a_i \in \mathbb F$ all distinct and $P$ a polynomial of degree $k-1$ with coefficient vector $\vec u\in\mathbb F^k$. Now, we construct a $(n,k',d'_{min})$ code $\mathcal C'$ similarly to the above one by assigning $a_1\leftarrow a_2$ while leaving $n,P$ and $a_2,\ldots,a_n$ unchanged. As before, the code is generated by evaluating $P_{\vec u}(a_2,a_2,a_3,\dots,a_n)$ over all possible coefficients vectors $\vec u \in \mathbb F^k$. This is by definition not an RS code, however it is still a well-defined linear block code. True or false: We know for certain that $d'_{min}=d_{min}-1$.

Let $\xv, \wv, \deltav \in \R^d$, $y \in \{-1, 1\}$, and $ arepsilon \in \R_{>0}$ be an arbitrary positive value. Which of the following is NOT true in general:
A. $rgmax_{\|\deltav\|_2 \leq arepsilon} \log_2(1 + \exp(-y \wv^ op (\xv + \deltav))) = rgmax_{\|\deltav\|_2 \leq arepsilon} \exp(-y \wv^ op (\xv + \deltav ))$
B. $rgmax_{\|\deltav\|_2 \leq arepsilon} \log_2(1 + \exp(-y \wv^ op (\xv + \deltav))) = rgmin_{\|\deltav\|_2 \leq arepsilon} y \wv^ op (\xv + \deltav )$
C. $rgmax_{\|\deltav\|_2 \leq arepsilon} \log_2(1 + \exp(-y \wv^ op (\xv + \deltav))) = rgmax_{\|\deltav\|_2 \leq arepsilon} 1 - anh(y \wv^ op (\xv + \deltav))$ \ where $ anh(z) = rac{e^z - e^{-z}}{e^z + e^{-z}}$
D. $rgmax_{\|\deltav\|_2 \leq arepsilon} \log_2(1 + \exp(-y \wv^ op (\xv + \deltav))) = rgmax_{\|\deltav\|_2 \leq arepsilon} \mathbf{1}_{y \wv^ op (\xv + \deltav) \leq 0}$
