iteration.

📗 Game
➭ Number of influencers \(n\):
➭ Number of victims \(m\):
➭ Influencer network \(I \in \left[0, 1\right]^{n \times n}\):
➭ Influence weights \(W \in \left[0, 1\right]^{n \times m}\):
➭ Victim network \(V \in \left[0, 1\right]^{m \times m}\):
➭ Victim weights \(U \in \left[0, 1\right]^{m \times n}\):
➭ Influencer targets \(t\):

📗 Equilibrium
➭ Influencers positions \(x\):
➭ Victims positions \(y\):

➭ Victims best response dynamics:

📗 Parameters
➭ Influencer \(i\)'s payoff given action \(x_{i}\): \(\displaystyle\sum_{j'} W\left(i, j'\right) \left\|t_{i} - y_{j'}\right\|^{2} + \lambda \displaystyle\sum_{i'} I\left(i, i'\right) \left\|x_{i} - x_{i'}\right\|^{2}\)
➭ Victim \(j\)'s payoff given action \(y_{j}\): \(\displaystyle\sum_{i'} U\left(j, i'\right) \left\|y_{j} - x_{i'}\right\|^{2} + \rho \displaystyle\sum_{j'} V\left(j, j'\right) \left\|y_{j} - y_{j'}\right\|^{2}\)
