In practical computing anticipatory systems, the efficiency of anticipatory reasoning engine is a key issue to satisfy the real-time requirements from applications. FreeEnCal: a forward reasoning engine for general-purpose purpose is a hopeful candidate for anticipatory reasoning engines. However, the current FreeEnCaJ is not efficient enough for practical computing anticipatory systems. This paper presents a new implementation of FreeEnCal improved by adopting fast algorithms, and shows its efficiency by comparing the improved FreeEnCal with the old one. The improved FreeEnCal can be used as an anticipatory reasoning engine of practical computing anticipatory systems.

The reactability of a persistent computing system, which is how many reactions of the system are active at a certain time, is the most important property to characterize the system. On the other hand, to be anticipatory, the reactability of a computing anticipatory system must be continuous. This paper proposes the first method to measure the continuous reactability of a persistent computing system in a unified way. The continuous reactability of a persistent computing system is a new concept of computing systems, so that it will be raise new research problems of computing anticipatory systems as well as persistent computing systems.
