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.
