<font color="#FF0000">EO Tutorial</font></h1></center>
Welcome to EO - the Evolving Objects library. What is this tutorial good
for?
<br>Well,&nbsp; the short term idea here is to help you <font color="#FF6600">build
your own Evolutionary Algorithms</font> using EO - while the long term
idea is that you will be able to contribute to EO, and ultimately write
<font color="#FF6600">our</font>
EAs :-)
<h3>
<b><font color="#000099"><font size=+2>About this tutorial</font></font></b></h3>
This tutorial can be used in 2 different ways: algorithm-based and component-based.
<ul>
<li>
<a href="eoTopDown.html">Algorithm-Based</a> means you start from a <font color="#FF6600">very
simple, ready-to-run algorithm,</font> and gradually modify it, making
it both more powerful and more complex.</li>
<li>
<a href="eoBottomUp.html">Component-Based</a> means you start by examining the
<font color="#FF6600">components
of an EA one by one</font>, down to the level of complexity you feel comfortable
with, and then build the whole algorithm using those components you need
(or the one you are mastering). Such approach might be viewed as going
through a simplified user guide, too.</li>
</ul>
However, it is <b><font color="#FF6600">strongly recommended</font></b>
that you take some time on the first lesson of the Algorithm-Based approach to
get familiar with the basic concepts that are used throughout EO. Anyway,
as of today, November 29, the Component-Based is not written yet :-)
<p><b><font color="#000099"><font size=+2>Related documents</font></font></b>
<ul>
<li>
There are of course a few (very few) <a href="eoProgramming.html">programming
hints</a> that you should know.</li>
<li>
THe <a href="../../doc/html/index.html">EO documentation </a>- automatically
generated from the comments in the code - is very helpful, to get an idea
of the inheritance diagrams of EO classes, and to quickly reach some specific
part of the code.</li>
<br>The top page of each class documentation is for instance the inheritance
diagram of the class, and you'll learn a lot by simply looking at it.
<li>
And, last but not least, we assume you know approximately that an Evolutionary
Algorithm looks like this, but otherwise you can try this <a href="eoIntroEA.html">very
brief introduction</a>).</li>
</ul>
<p><br><b><font color="#000099"><font size=+2>Colors and navigation:</font></font></b>
<p>You will see this diagram in quite many places, as for instance at the
top of all examples - usually it will be clicable and will help you navigate
among the different parts of an EO program. See the <a href="eoIntroEA.html">brief
introduction to Evolutionary Computation</a> for a detailed explanation.

<a NAME="colors"></a>
<p>But in the text itself, <b><font color="#FF6600">colors are important</font></b>,
as they will be used throughout this tutorial to clearly mark which part
of the algorithm we are discussing. So please keep in mind that, whereas
<font color="#FF6600">orange
is for emphasis</font>,
<ul>
<li>
<b><font color="#999900">Yellowish</font></b> is for <b><font color="#999900">representation</font></b>,
i.e. the choice of the <b><font color="#999900">genotype</font></b></li>
<li>
<font color="#CC33CC">Magenta</font> is for the <font color="#CC33CC">stochastic
operators</font> that are <b><font color="#999900">representation-dependent</font>,</b>
i.e. <font color="#CC33CC">initialisation</font> and variation operators
(<font color="#CC33CC">crossover</font>, <font color="#CC33CC">mutation</font>
and the like).</li>
<li>
<font color="#009900">Green</font> is for the implementation of <font color="#009900">Darwinism</font>,
i.e. the way the individuals are <font color="#009900">selected</font>
for reproduction and <font color="#009900">survive.</font></li>
<li>
<font color="#CC0000">Red</font> is for evaluation, i.e. the computation
of the <font color="#CC0000">fitness</font> of all individuals</li>
<li>
<font color="#3366FF">Blue</font> is for interactions of the user and the
program, as for instance choice of <font color="#3366FF">stopping criterion</font>,
on-line display of nice <font color="#3366FF">statistics</font> or initial
<font color="#3366FF">choice
of all program parameters</font>.</li>
<li>
<font color="#993300">Brown</font> is for everything that is NOT part of
any of the above, i.e. random number generator, or basic C++/STL syntax
.</li>
<li>
Note that <font color="#FF6666">pink</font> will be used to desctibe the
syntax of compile orders (i.e. at the oepratoring system level, see e.g.
<a href="#install">below</a>).</li>
<li>
<font face="Arial,Helvetica">Last, but not least, all links into EO documentation
will use the Helvetica typeface, like this line you are now reading.</font></li>
</ul>
<ul>
<li>
an interface that would allow you to build your Evolutionary Programs by
a few clics; such a thing does exist, is called <a href="http://www-rocq.inria.fr/EASEA/">EASEA</a>,
and is complementary to this tutorial as it helps the user to build some
simple EO programs from simple description. But there are things that EASEA
cannot do, and you will have to do it yourself and will need to imcrease
your knowledge about EO for that.</li>
</ul>
<a NAME="install"></a>
<h3>
<font color="#000099">Before you start</font></h3>
You should of course have downloaded and installed the whole <a href="http://www.sourceforge.net/projects/eodev">EO
library</a> (how did you get this file if not???).
<br>So we'll assume that you are now in the Tutorial directory, and that
your prompt looks something like
<p><b><tt><font color="#FF6666">(myname@myhost) EOdir/Tutorial %</font></tt></b>
<p>so you should now type in
<p><b><tt><font color="#FF6666">make lesson1</font></tt></b>
<p>and see something like
<p><font face="Courier New,Courier"><font color="#000000">(myname@myhost)
EOdir/Tutorial % make lesson1</font></font>
<br><b><tt><font color="#FF6666">c++ -DPACKAGE=\"eo\" -DVERSION=\"0.9.1\"
-I. -I../../src -Wall -g -c FirstBitGA.cpp</font></tt></b>
<br><b><tt><font color="#FF6666">c++ -Wall -g -o FirstBitGA FirstBitGA.o
../../src/libeo.a ../../src/utils/libeoutils.a</font></tt></b>
<br><b><tt><font color="#FF6666">c++ -DPACKAGE=\"eo\" -DVERSION=\"0.9.1\"
-I. -I../../src -Wall -g -c FirstRealGA.cpp</font></tt></b>
<br><b><tt><font color="#FF6666">c++ -Wall -g -o FirstRealGA FirstRealGA.o
../../src/libeo.a ../../src/utils/libeoutils.a</font></tt></b>
<p>and two now executable files should have appeared in the subdirectory
Lesson1, namely <b><tt><font color="#990000">FirstBitGA</font></tt></b>
and <b><tt><font color="#990000">FirstRealGA</font></tt></b> (see <a href="eoLesson1.html">First
lesson</a> to know more about these two ready-to-run programs). If this
doesn't work, please go back to the main EO directory and run the installation
program.
<p>You should also test that you can access the EO documentation in the
menu line below: you might not need to go there immediately, but just in
case you make rapid progress ... This menu bar should be on all pages of
this tutorial, allowing you to navigate easily.
<p>Last, but not least: EO is improving only&nbsp; from the good will of
contributors. This is also true for this tutorial: If you find anything
that you think could be improved, you are welcome to <a href="mailto:Marc.Schoenauer@polytechnique.fr">e-mail
me</a>.
