s \(X_i\) in this problem indicate whether
each project \(i \in I\) is funded or not. The decision
variables in this problem are the \(Y_{j}\), \(Z_{fj}\), \(E_f\),
and \(G_f\) variables.
Specifically, the binary \(Y_{j}\) variables indicate if project \(j\)
is funded or not based on which actions are funded; the binary
\(Z_{fj}\) variables indicate if project \(j\) is used to manage
feature \(f\) or not; the semi-continuous \(E_f\) variables
denote the probability that feature \(f\) will go extinct; and th
