This lp decoder can be used to decode errorcorrecting codes at biterrorrates comparable to stateoftheart belief propagation bp decoders, but with significantly stronger theoretical guarantees. A major benefit of story decomposition is the ability to provide smaller items of functionality quicker, and receive faster feedback from the businessend user than if functionality were batched together in a larger story that made more sense from an implementation standpoint. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere.
