The probability density \( {\rho}_{x_0}(t) \) of the FPT to the absorbing node x_a = 1 on a chain graph with N = 100 nodes with the reflecting node at x = 100. Travel time distributions are fixed to be \( {\tilde{\psi}}_{x{x}^{\prime }}(s)=1/\left( s\tau +1\right) \) with τ = 1 in all nodes x except the trap node x_h located either at 25, or at 75, at which \( {\tilde{\psi}}_{x_h{x}^{\prime }}(s)=1/\left({s}^a{\tau}^a+1\right) \); a = 0.5. The starting point is located at x₀ = 50. The additional link is placed around the trap x_h = 25
