|Genetic Algorithms at Work: Two Case Studies -- Michael J. Lipon,
Howard P. Rosenof and Gerald Liston - Genetic Algorithms can combine with
knowledge-based technologies to produce powerful applications. these applications
are extremely useful in industries which must schedule batch process operations.
| Concepts of Modeling and Simulation -- Bob Diamond - Models and
simulations play important roles in numerous areas. Although they can become
complex, their foundational principlesare surprisingly comprehensible.
|Mind Tools: Connecting to Groupware -- Daniel W. Rasmus - Groupware
holds the potential of new ways to manage conversations in a digital world.
The potential is being fulfilled, as innovative groupware applications are
redefining computer-based collaboration.

New Focus, New Dimensions
| This issue brings a new dual focus to PC AI, and with it a new
dimension. As we present for the first time, "Genetic Algorithms/Modeling,"
we expand the set and style of the technologies we cover.
| Genetic Algorithms (GAs) simulate Darwinian evolutionary processes. A
GA generates a population of entities which correspond to possible solutions
to a specific problem. The GA evaluates the "fitness" of each one. The fittest
"survive" as the GA produces another "generation" of solutions. The objective
is to evolve the best solution after numerous iterations of generation production
and fitness evaluation.
| "Modeling" is the use of a well-understood phenomenon to shed light on
a phenomenon which is not understood. The first (the "model") mimics the
second. Scientists often use equations as models of natural processes. Analyzing
the equations leads to understanding the processes.
| The new dimension in our future is the coverage of many varieties of
modeling tools. In the issues to come, we'll describe industrial-strength
tools which can help o physical scientists examine the interacting forces
in the world around us o social scientists understand the nature and ramifications
of human behavior o large and small businesses comprehend the events which
drive the bottom line.
| Two articles and a review fall within the new focus. In "Genetic Algorithms
at Work" Michael Lipton, Howard Rosenof, and Gerard Liston present two case
studies. The (coincidentally) related industries they examine show how GAs
combine with knowledge-based technologies to solve important business problems.
In "Concepts of Modeling and Simulation" Bob Diamond brings you the basics
and distinguishes among the major categories of model-building. "Statistical
Modeling Takes Off" reviews SPSS 6.1 for Windows, a package that facilitates
potentially complex modeling and analysis.
| Our other offerings are timely. Mary Kroening's "Web-Based Intelligent
Tech Support" shows how Artificial Intelligence technology can reside on
the World-Wide Web and perform crucial tasks related to customer service.
Dan Rasmus' "Mind Tools: Connecting to Groupware" gives us a valuable view
of the groupware landscape. He reports on new products that help us communicate
and collaborate in today's digital world. Hal Berghel's "Cybernautica" clarifies
the vagaries of the Common Gateway Interface (CGI). Our extensive Product
Updates and Buyer's Guide round out the picture.
| As is appropriate in an issue on Genetic Algorithms, our magazine's evolution
continues unabated. Two new staff members have already made major impacts.
Editorial Assistant Linda Finecey has streamlined the editing process and
catalyzed welcome changes which are visible throughout the issue. Web Editor
Liz Olsen has started upgrading our Web site and will maintain its currency.
We look forward to working with Linda and Liz as they help us add new dimensions
in the years to come.
