Identifying a temporal pattern of events is a fundamental task of on-line (real-time) verification. In this work we present efficient schemes for on-line monitoring of events for identifying predefined patterns of events. The schemes use preprocessing to ensure that the number of comparisons during run-time is minimized. In particular, obsoloete sub-sequences are discarded to avoid unnecessary comparisons.We use our monitoring scheme for estimating the probability that a random suffix of a given execution will contain the pattern.
