Computation of the efficiency of the Mosely-Humblet contention resolution algorithm: A simple method

Mosely and Humblet have obtained an efficient Contention Resolution Algorithm for transmission scheduling in a multi-user collision channel with ternary feedback (idle, success, collision). In this letter, a recursion for the expected value of the algorithm cycle delay is shown to reduce the computation of the efficiency and optimum partition functions to a simple optimization problem.
