<font color="#FF0000">EO Tutorial</font></h1></center>
<center><font color="#FF0000">Important notice - December 2006</font>
</center><br>
The code that is proposed in this tutorial should <font color="#FF0000"><b>not</b></font>
be used
as a basis for any comparison with any original method on any benchmark problem.
It is an illustration of what you can achieve with EO, but reaching state-of-the-art results
requires more work. In particular, if you want to compare your evolutionary
algorithm with a good performing algorithm in parameteric optimisation,
do <font color="#FF0000"><b>not</b></font>
use <font color="#FF6666"><b>ESEA</b></font> in Lesson4,
but go to the <font color="#FF6666"><b>test</b></font> directory, type
<font color="#FF6600"><b>make t-eoCMAES</b></font> and use the resulting <font
color="#FF6666"><b>t-eoCMAES</b></font>. But as of today,
the latest algorithms (and comparative results)
are better found on <a href="http://www.bionik.tu-berlin.de/user/niko/">Nikolaus Hansen Web page</a>
and on his <a href="http://www.bionik.tu-berlin.de/user/niko/cec2005.html">"Comparison of Evolutionary Algorithms on a Benchmark Function Set" page</a>).<br>
<br>
<br>
<center><font color="#FF0000">Version 0.98a - December 2004</font>
</center>
<ul>
<li><b><font color="#FF0000">New</font></b> -
Well, in fact, nothing really new,
but some people advised us to announce from the very beginning that
if you are looking for a <font color="#FF0000"><b>ready-to-use</b></font>
(except for the fitness) <font color="#FF0000"><b>fully tunable Evolutionary
Algorithm</b></font> evolving real values or bitstring, you can
<font color="#FF0000"><b>go directly to</font><font color="#000000">
<a href="eoLesson4.html">Lesson 4</a></font></b> after just reading
this page, and maybe the <a href="eoProgramming.html">Programming
hints</a> (link on top of each page too). <br/>
In fact, there is something new: EO's automatic configuration and
build process has been cleaned up and upgraded. For consistency, the
same automatically-built <tt><font
color="#FF6666"><b>Makefiles</b></font></tt> have been created in the
tutorial directories. The good-old manually-created files are
still there, now named
<tt><font color="#FF6666"><b>Makefile.simple</b></font></tt>.
Moreover, when you compile the whole library (typing <font color="#FF6600"><b>make</b></font> in the main EO dir), all lessons of the tutorial gets compiled, too.

<center><font color="#FF0000">Version 0.98 - May 2004</font></center>
</b>
<li><b><font color="#000000"><a href="eoLesson5.html">Lesson 5</a>
</font></b><font color="#000000">has been improved: some of
the empty template files in dir
<b><tt><font color="#FF6666"><b>.../eo/tutorial/Templates</b></font></tt></b>
have been simplified, and file <font color="#3366FF"><b>stat.tmpl</b></font>
has been added, allowing you to
<font color="#FF6600"><b>compute</b></font> and
<font color="#FF6600"><b>print</b></font> and
<font color="#FF6600"><b>save-to-disk</b></font> and
<font color="#FF6600"><b>plot-on-line</b></font> your
own <font color="#3366FF"><b>statistics</b></font>.
The magic script is now (see Lesson5) <b><tt><font color="#993300">createSimple</font></tt></b>.<br>
The same simplified main file in
dir <b><tt><font
color="#FF6666"><b>.../eo/tutorial/Templates</b></font></tt></b>)
also allows you to use
<font color="#FF6600"><b>fitness sharing</b></font>
(together with roulette wheel) as a possible selector.<br>
Unfortunately, the HTML file for Lesson5 and the corresponding
html-ized code are not yet updated - time is missing
(volunteers welcome).<br><br>

<center><b>Welcome to EO tutorial/on-line documentation.</b></center>
<hr WIDTH="100%"><b><h2><font color="#000099">About this tutorial</font></b></h2>
First, please note that <b><font color="#FF6600">this tutorial is <font color="#FF0000">not</font> supposed
to be printed and read off-line</font></b>, as it takes full advantage
of hyper-text links between the different parts, and with the technical
documentation.
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, December 19, the Component-Based is only very sparsely written
:-)
<p>
<hr WIDTH="100%"><b><font color="#000099"><font size=+2>Links and 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 <b><font color="#FF6600">inheritance diagrams</font></b> 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>
For those who wish to get deeper in STL (Standard Template Library), you
might visit the well documented <a href="http://www.sgi.com/Technology/STL/">SGI
STL Web site</a>. But don't forget you'll find the very basic minimum in
EO <a href="eoProgramming.html#STL">programming hints</a>.</li>
<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> (not written yet, Jan. 2001, sorry).</li>
</ul>
<p><br>
<hr WIDTH="100%"><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 clickable 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.

<p><img SRC="EA_tutorial.jpg" ></center>
<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
<b><font color="#FF6600">orange
is for emphasis</font></b>,
<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 describe the
syntax of compile orders (i.e. at the operating system level, see e.g.
<a href="#install">below</a>).</li>
<li>
<b><font face="Arial,Helvetica"><font size=+1>Last, but not least, all
links into EO documentation will use the Helvetica typeface, like this
line you are now reading.</font></font></b></li>
</ul>
<hr WIDTH="100%"><b><font color="#000099"><font size=+1>This tutorial is
not</font></font></b>
<ul>
<li>
A course on Evolutionary Computation. You can find such things on the Internet,
maybe you can start <a href="http://www.evonet.polytechnique.fr/CIRCUS2/node.php?node=240">here.</a></li>
<li>
An interface that would allow you to build your Evolutionary Programs by
a few clicks; 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 increase
your knowledge about EO for that - hence this tutorial.</li>
<li>
A coffee machine - though you might want to spend some time here when you're
tired of everything else, to improve your knowledge of EO slowly and gradually
rather than when you have something urgent to code :-)</li>
</ul>
<hr WIDTH="100%"><a NAME="install"></a><b><font color="#000099"><font size=+1>Before
you start</font></font></b>
<p>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???).
If you are using a recent version of EO (0.9.3+), all tutorial Lessons
should have been compiled when installing the library, and you can now
proceed with <a href="eoLesson1.html">Lesson1</a>. <br>
<br>Otherwise, 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@inria.fr">e-mail
me</a>.
