We have implemented a basic prototype program, and from that created and tested several alternate versions, all with the purpose of improving some part of the algorithm. We have achieved good results and our best version has approximately cut the original running time in half, while losing almost nothing in compression effectiveness, and even lowering memory use significantly." }
