A s more and more economic activity shifts to service industries, meaningful evaluation of their "product" is Abecoming a topic of major concern. The service organization is constantly being evaluated by its customers and it is important for management to understand bases for this evaluation. In the case of the general purpose time-sharing system, there may in fact be several different groups o...

The Computer Measurement Group, commonly called CMG, is a not for profit, worldwide organization of data processing professionals committed to the measurement and management of computer systems. CMG members are primarily concerned with performance evaluation of existing systems to maximize performance (eg. response time, throughput, etc.) and with capacity management where planned enhancements ...

This paper introduces Sentient Sketchbook, a tool which supports a designer in the creation of game levels. Using map sketches to alleviate designer effort, the tool automates playability checks and evaluations and visualizes significant gameplay properties. Most importantly, this paper introduces constrained novelty search via a two-population paradigm for generating, in real-time, alternative...

We describe a topic tracking system developed at GE R&D Center in connection with our participation in DARPA TDT evaluations. The TDT tracking task is specified as follows: given Nt training news stories on a topic, the system must find all subsequent stories on the same topic in all tracked news sources. These sources include radio and television news broadcasts, as well as newswire feeds. The...

This paper discusses the way of processing time-series subsequence matching under time warping. Time warping enables sequences to be found with similar patterns even when they are of different lengths. The prefix-querying method is the first index-based approach that efficiently performs time-series subsequence matching under time warping without false dismissals. This method employs the L dist...

We extend the methods of Van der Poorten and Chapman [7] for explicitly evaluating the Dedekind eta function at quadratic irrationalities. Via Hecke L-series we obtain evaluations in some new cases. Specifically we provide further evaluations at points in imaginary quadratic number fields with class numbers up to four. We also describe techniques, which make use of modular equations, which prov...

Graph searching problems are described as games played on graphs, between a set of cops and a fugitive. Variants of the game restrict the abilities of the cops and the fugitive and the corresponding search numbers (the least number of cops that have a winning strategy) are related to several well-known parameters in graph theory. We study the case where the fugitive is visible (the cops’ strate...
