This paper revisits earlier work on the achievable rate-region for the coded side-information problem. For specific source distributions we provide computable extreme rate points. As opposed to previous works, we present short and concise proofs and additional rate points below the time-sharing line of previously known rate points. Our results are based on a formulation as an optimization problem.
