About Graph Energy Calculator

A graph energy calculator computing E(G) = Σ|λᵢ|, the sum of absolute values of adjacency matrix eigenvalues. Introduced by Gutman (1978) for molecular orbital theory. E(K_n) = 2(n-1). Hyperenergetic: E(G) > E(K_n). Integral energy: all eigenvalues integer. Client-side.
