Evolutionary algorithms are a type of general problem solvers that can be applied to many
difﬁcult optimization problems. Because of their generality, these algorithms act similarly
like Swiss Army knife (Michalewicz & Fogel, 2004) that is a handy set of tools that can be
used to address a variety of tasks. In general, a deﬁnite task can be performed better with an
associated special tool.
However, in the absence of this tool, the Swiss Army knife may be
more suitable as a substitute. For example, to cut a piece of bread the kitchen knife is more
suitable, but when traveling the Swiss Army knife is ﬁne.
Similarly, when a problemto be solved froma domain where the problem-speciﬁc knowledge
is absent evolutionary algorithms can be successfully applied. Evolutionary algorithms are
easy to implement and often provide adequate solutions.

A mobile phone is a Swiss Army knife. It is not a chef’s knife or a buck
knife. We keep wanting new features on the phone, like texting, voice
memos, browsing, a camera, music, and television, because we would
like these things in our pocket and the phone is already there.
Perl is the ever-popular, flexible, open source programming language that has been called the programmers’ Swiss army knife. This book introduces Perl to both new programmers and experienced ones who are looking to learn a new language. In the tradition of the popular Wrox Beginning guides, it presents step-by-step guidance in getting started, a host of try-it-out exercises, real-world examples, and everything necessary for a Perl novice to start programming with confidence.
