Abstract
We give a detailed algorithm for fast text compression. Our algorithm, related to the PPM method, simplifies the modeling phase by eliminati ng the escape mechanism and speeds up coding by using a combination of quasi-arithmetic coding and Rice coding. We provide details of the us e of quasi-arithmetic code tables, and analyze their compression perfo rmance. Our Fast PPM method is shown experimentally to be almost twice as fast as the PPMC method, while giving comparable compression.
