Energy–graph-entropy distance conjecture for trees

Let TT and TT' be any two trees with nn vertices. Energy–graph-entropy distance conjecture. It holds

dE(T,T)dIg(T,T).d_E(T,T')\geq d_{Ig}(T,T').

Here EE is the graph energy and IgIg is the entropy based on the absolute adjacency-matrix eigenvalues. The conjecture was verified for trees with a small number of vertices, but the paper gives counterexamples with more than 1212 vertices.
