Consider the neural network shown in the figure with inputs: $u, v$ weights: $a, b, c, d, e, f$ output: $y$ R denotes the ReLU function, $\mathrm{R}(x)=\max (0, \mathrm{x})$.

Given $u=2, v=3$, $a=1, b=1, c=1, d=-1, e=4, f=-1$, which one of following is correct?

Consider game trees Tree-1 and Tree-2 as shown. The first level is a MAX agent and the second level is a MIN agent. The value in the square node is the output of the utility function.
