Cost Function Matching
Consider the following cost functions. What purpose does each serve?
Cost Function 1
\begin{cases}
1 & \ddot{s} \geq a\_{\text{max}} \\
0 & \ddot{s} < a\_{\text{max}}
\end{cases}
Cost Function 2
\begin{cases}
1 & d \geq d\_{\text{max}} \\
1 & d \leq d\_{\text{min}} \\
0 & d\_{\text{min}} < d < d\_{\text{max}}
\end{cases}
Cost Function 3
\begin{cases}
1 & \dot{s} \geq v\_{\text{speed limit}} \\
0 & \dot{s} < v\_{\text{speed limit}}
\end{cases}
Cost Function 4
\frac{1}{1 + e^{-(d - d\_{\text{lane center}})^2}}
Cost Function 5
(\text{lane number} - \text{target lane number}) ^ 2
