Consider a network that follows the Barabási-Albert model with \(m_0 = m = 2\). A node \(i\) joined the network at time \(t_i = 375\) and has degree \(k_i(t) = 40\) at the current time step. What is the expected diameter of this network now? Round to two decimal places.

  1. \(\langle D \rangle \approx 4.20\)
  2. \(\langle D \rangle \approx 4.81\)
  3. \(\langle D \rangle \approx 2.80\)
  4. \(\langle D \rangle \approx 3.81\)
  5. None of the above
