Distributed Storage Allocation Problems [PDF]
, 2009 We investigate the problem of using several storage nodes to store a data object, subject to an aggregate storage budget or redundancy constraint. It is challenging to find the optimal allocation that maximizes the probability of successful recovery

A Discrete-Binary Transformation of the Reliability Redundancy Allocation Problem [PDF]
Mathematical Problems in Engineering, 2015 Given a reliability redundancy optimization problem in itsdiscreteversion, it is possible to transform such integer problem into a correspondingbinaryproblem in log-time. A simple discrete-binary transformation is presented in this paper. The proposed transformation is illustrated using an example taken from the reliability literature.
