An argument for Hamiltonicity

Vadym Fedyukovych

Abstract: A constant-round interactive argument is introduced to show existence of a Hamiltonian cycle in a directed graph. Graph is represented with a characteristic polynomial, top coefficient of a verification polynomial is tested to fit the cycle, soundness follows from Schwartz-Zippel lemma.
