<p>Tournaments are an easy and quick way to <b><font color="#FF6600">select</font></b>
individuals within a population based on simple comparisons. Though usually
based on fitness comparisons, they can use any comparison operator.
<br>In EO, there are two variants of tournaments used to select one single
individual, namely <b><tt><font color="#009900">Deterministic Tournament</font></tt></b>
and <b><tt><font color="#009900">Stochastic Tournament</font></tt></b>,
that are used in selection and in replacement procedures, and a global
tournament-based selection of a whole bunch of individuals, the <b><tt><font color="#009900">EP
Tournament</font></tt></b>. Though the single-selection tournaments can
be repeated to select more than one individual, and the batch tournament
selection can be used to select a single individual, both uses are probably
a waste of CPU time.
<ul>

<b><tt><font color="#009900">Deterministic Tournament</font></tt></b> of

a global tournament: it works by assigning a score to all individuals in
the population the following way: starting with a score of 0, each individual
I is "opposed" T times to a uniformly chosen individual. Everytime I wins,
its score in incremented by 1 (and by 0.5 for every draw). The individuals
are then selected deterministically based on their scores from that procedure.

<p>Many classes in selection/replacement procedures will handle a number
of individuals that may either be fixed or be a fraction of some argument-population
size.
<br>Of course, it is possible to write two different classes that will
only differ by the way they compute the number of individuals they have
to treat, as it is done for selectors with the two classes <font color="#009900">eoSelectPerc</font>
and <font color="#009900">eoSelectNumber</font> (it could also have been
possible to have some pure abstrat class and implement the computation
of the number of individuals to treat in some derived classes).
<br>However, rather than multiply the number of class, EO has defined a
class that will handle the problem once and for all, the class <b><tt><font color="#993300">eoHowMany</font></tt></b>.
It receives a <b><tt><font color="#993300">double</font></tt></b>, and
a <b><tt><font color="#993300">boolean</font></tt></b> indicating whether
that double is to be treated <b><font color="#FF6600">as a rate</font></b>

<br>Variation operators modify individuals, or, equivalently, move them
in the search space. They are almost always <b><font color="#FF6600">stochastic</font></b>,
i.e. they are based on random numbers, or equivalently, perform random
modifications of their arguments. Variation operators are classified depending
on the number of arguments they use and/or modify.
<p>Variation operators involving two individuals are called <a href="#crossover">crossover
operators</a>. They can either modify one of the parents according to the
material of the other parent, or modify both parents. In EO, the former
are called Binary operators and the latter Quadratic operators.
<br>Variation operators involving one single individual are called <a href="#mutation">mutation
operators.</a>
<br>In EO you can also define and use variation operators that generate
any number of offspring from any number of parents (sometimes termed <b><font color="#FF6600">orgy</font></b>
operators). They are called <a href="#general">general operators</a>.
<p>Though most the historical evolutionary algorithms used at most one
crossover and one mutation (see e.g. the Simple Genetic Algorithm in <a href="eoLesson1.html">lesson1</a>),
the trend now in evolutionary computation is to combine operators, choosing
at run-time and for each individual which operator to apply. This can be
done in the framework of simple operators, combining for instance several
mutations into a variation operator that chooses one of them according
to user-defined preferences: such combinations are called in EO <a href="#proportional_simple">proportional
combination of simple operators</a> (see e.g. how to define and use such
combined operators in the SGA of <a href="eoLesson2.html">lesson2</a>).
<p>Finally, there are many other ways to combine different variation operators
of different kind. Within EO, you can choose to apply many different types
of operator to the population, either in turn (this is called sequential
combination) or by randomly choosing among a set of operators at a given
time (this is proportional combination, generalizing the one defined for
simple operators). You can of course mix and interleave both approaches
at will, and this is described as <a href="#general_combination">general
combination of general operators</a>.

in the search space. In Evolutionary Algorithms, varitaion operators are
almost always <b><font color="#FF6600">stochastic</font></b>, i.e. they
are based on random numbers, or equivalently, perform random modifications
of their arguments. Variation operators are classified depending on the
number of arguments they use and/or modify.

<li>
Variation operators involving <b><font color="#FF6600">two individuals</font></b>
are called <a href="#crossover">crossover operators</a>. They can either
modify one of the parents according to the material of the other parent,
or modify both parents. In EO, the former are called Binary operators and
the latter Quadratic operators.</li>
<li>
Variation operators involving <b><font color="#FF6600">one single individual</font></b>
are called <a href="#mutation">mutation operators.</a></li>
<li>
Straightforward extensions of these simple operators allow to combine them:
in
<a href="#proportional_simple">proportional combinations</a>, one operator
is chosen among a given set of operators of same arity according to some
weights.</li>
<li>
In EO you can also define and use variation operators that generate any
number of offspring from any number of parents (sometimes termed <b><font color="#FF6600">orgy</font></b>
operators). They are called <a href="#general">general operators</a>.</li>
<li>
However, the interface of such operators was designed for their use inside
<a href="#general_combination">general
combinations</a>: you can use <b><font color="#FF6600">proportional combination</font></b>,
in which one operator is chosen among a given set of operators of same
arity according to some weights, as for simple operators except that operators
of different arities can be mixed, but you can also use <b><font color="#FF6600">sequential
combinations</font></b>, where different operators&nbsp; are applied in
turn with given probability. But you can also embed any of such combinations
at any depth.</li>
<li>
The price to pay for that is that you must use an instermediate class to
access the individuals, the <a href="#populators">eoPopulator</a> class.</li>
<li>
Thanks to that class, it also become easy to design <a href="#advanced_general">advanced

<p>General operators in EO are variation operators that are neither simple
mutations nor simple crossovers. They can involve any number of parents,
and create any number of offspring. Moreover, they can make use of different
ways to get the parents they will involve, e.g. they can use a different
selector for each of the parents they need to select.
<p>The corresponding EO class is called <b><font color="#CC33CC">eoGenOp</font></b>.

</font></b>An
<b><font color="#999900">eoPopulator</font></b>
is a <b><font color="#FF6600">population</font></b>, but also behaves like
an <b><font color="#FF6600">iterator</font></b> over a population (hence
the name, <b><font color="#FF6600">Popul</font></b>ation-Iter<b><font color="#FF6600">ator</font></b>).
<p><a NAME="populator_interface"></a>The <b><font color="#FF6600">basic
interface</font></b> of an <b><font color="#999900">eoPopulator</font></b>
(see also <a href="../../doc/html/class_eogenop.html">the documentation</a>,
of course) is the following: Individuals are accessed through the <b><tt><font color="#993300">operator*</font></tt></b>;
Basic iterator operations are available, like (pre)incrementation through
<b><tt><font color="#993300">operator++</font></tt></b>,
position management through <b><tt><font color="#993300">seekp</font></tt></b>
(returns the current position) and <b><tt><font color="#993300">tellp</font></tt></b>
(go to a given position); Individuals can also be <b><font color="#993300">insert</font></b>ed
and <b><font color="#993300">erase</font></b>d at current position using
the corresponding methods; last but not least, as the individuals are returned
by reference, it is mandatory to ensure that they will not be moved around
later: the memory management&nbsp; routine reserve is called whenever there
is a chance to add some individuals in the population.
<p>This results in the following general interface for an <b><font color="#CC33CC">eoGenOp</font></b>:
It receives as argument an <b><font color="#999900">eoPopulator</font></b>,
gets the individuals it needs using the <b><tt><font color="#993300">operator*</font></tt></b>,
and must handle the positinning of the&nbsp; using the <b><tt><font color="#993300">operator++</font></tt></b>

<br><b><tt><font color="#993300">}</font></tt></b>
<p><b><font color="#FF6600">What happens next?</font></b> Well, it all
depends on how many parents and how many offspring your general op needs:
<ul>
<li>
If the number of generated offspring is <font color="#FF6600">equal</font>
to the number of parents, the operator simply needs to modify them (they
are passed by reference, no useless copy takes place).</li>
<li>
If the operator produces <font color="#FF6600">more offspring than there
were parents</font>, it needs to insert them into the list using the <b><tt><font color="#993300">insert</font></tt></b>
method of the class <b><font color="#999900">eoPopulator</font></b> as
in the following:</li>
<br>&nbsp;
<p>
<p>&nbsp;
<p><b><tt><font color="#993300">void operator()(</font><font color="#999900">eoPopulator</font><font color="#993300">&amp;

<br><b><tt><font color="#993300">{</font></tt></b>
<br><tt><font color="#993300"><b>&nbsp; EOT &amp; eo1 = *_pop; </b>// get
(select if necessary) the guy</font></tt>
<br><tt><font color="#993300"><b>&nbsp; ++_pop;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</b>// advance</font></tt>
<br><tt><font color="#993300">&nbsp; // Now create second offspring - eo1
is modified too!</font></tt>
<br><b><tt><font color="#993300">&nbsp; EOT eo2 = create_individual(eo1);</font></tt></b>
<br><tt><font color="#993300">&nbsp; // inserts eo2 in _pop after eo1</font></tt>
<br><b><tt><font color="#993300">&nbsp; _pop.insert(eo2);</font></tt></b>
<br><b><tt><font color="#993300">...</font></tt></b>
<br>Of course the size of the resulting population will grow - and you
should have a replacement procedure that takes care of that.
<li>
The case where <font color="#FF6600">more parents are needed than offspring
will be created</font> is a little more delicate: think about <b><font color="#CC33CC">eoBinOp</font></b>,
and try to imagine the reasons why no crossover of that class asre used
in the first lessons of the tutorial, within the SGA framework. There are
two possibilities:</li>
<ul>
<li>
If you think "generational", the first idea is to get the parents from
outside the curent list, so the total number of (intermediate) offspring
is always equal to the initial population size. By chance, the <b><font color="#999900">eoPopulator</font></b>has
a handle on the initial population that was used to start the process,
and you can access it from inside the GenOp method. For instance
<p><b><tt><font color="#993300">void operator()(</font><font color="#999900">eoPopulator</font><font color="#993300">&amp;
_pop)</font></tt></b>
<br><b><tt><font color="#993300">{</font></tt></b>
<br><tt><font color="#993300"><b>&nbsp; EOT &amp; eo1 = *_pop; </b>// get
(select if necessary) the guy</font></tt>
<br><tt><font color="#993300"><b>&nbsp; ++_pop;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</b>// advance</font></tt>
<br><b><tt><font color="#993300">&nbsp; const EOT &amp; eo2 = </font><font color="#009900">select</font><font color="#993300">(_pop.source());</font></tt></b>
<p>where select is any selector you like. Note the const: you are not allowed
to modify an element of the original population (but you could of course
have copied it!). Now to find out where that selector comes from, you'll
have to wait until next section. If you can't wait, go directly there.</li>
<li>
If you don't care about the size of the offspring population, you can use

<b><font color="#FF6600">Warning</font></b>: if you use operators that
have different number of parents than offspring, you are deviating from
the simple generational approach. Be careful to have the proper replacement
procedure to take care of the population size: in most instances of algorithms
that come within EO, this is enforced (an exception is thrown if population
size varies from one genertaion to the other) but this might not be true
for all forthcoming EO algorithms.

populators:</font></font></b>
<br>The public interface class <b><font color="#999900">eoPopulator</font></b>
has been described above. However, a protected method, termed <b><tt><font color="#993300">select</font></tt></b>,&nbsp;
is used inside the object to get new parents for the following operator,
and its implementation distinguishes two types of <b><font color="#999900">eoPopulator</font></b>:
<ul>
<li>
The <b><font color="#999900">eoSeqPopulator</font></b> gets new parents
from its source (the initial population). When the source is exhausted,
an exception if thrown. The idea of such pooulator is to start from a population
of already selected individuals.</li>
<br>The programmer should hence be very careful that the number of available
parents matches the requirements of the operators when using an <b><font color="#999900">eoSeqPopulator</font></b>
object.
<li>
The <b><font color="#999900">eoSelectivePopulator</font></b> , on the opposite,
always gets new parents using its private <b><font color="#009900">eoSelectOne</font></b>
object (passed at construct time). Hence it can handle any number of parents
at will. The idea of such populator is to handle the whole <b><font color="#FF6600">breeding</font></b>
process, i.e. selection and variation operators.</li>
</ul>
An immediate consequence is that if you are not sure of the numebr of&nbsp;
parents you will need in some operators (e.g. because of some stochastic
proportional selection ebtween operators that don't need the same number
of parents, then you <b><font color="#FF6600">must</font></b> use an <b><font color="#CC33CC">eoSelectivePopulator</font></b>

iterates <b><tt><font color="#993300">while (!_pop.exhausted())</font></tt></b>
which is interpreted differently depending on the <a href="#populators">type
of <b><font color="#CC33CC">eoPopulator</font></b></a>:
<ul>
<li>
if the argument is an <b><font color="#999900">eoSelectivePopulator</font></b>,
the default position of the eoPopulator, considered as a population iterator,
is at end of population. Individuals are added upon demand of an operator,
and in most cases all operators are applied once. This also depends, however,
on the arities of all operators:</li>
<ul>
<li>
Consider an <b><font color="#CC33CC">eoSequentialOpContainer</font></b>
containing an eoQuadOp and an eoMonOp. The eoQuadOp first asks for two
parents and modifies them. The eoMonOp is then called starting from the
forst of thoses two modified individuals, and is hence applied twice, once
on each parent.</li>
<li>
But consider now an <b><font color="#CC33CC">eoSequentialOpContainer</font></b>
containing an <b><font color="#CC33CC">eoGenOp</font></b> that takes one
parent and generates three offspring, followed by an <b><font color="#CC33CC">eoQuadOp</font></b>.
The <b><font color="#CC33CC">eoGenOp</font></b> will call the selector
to get the parent its need and will modify it and put 2 additional offspring
at end of the population. The <b><font color="#CC33CC">eoQuadOp</font></b>
will then be called on the first of the three outputs of the <b><font color="#CC33CC">eoGenOp</font></b>,
and hence will act upon the frist two of them. But at that point, the populator
iterator will point to the third of the individuals resulting from the
<b><font color="#CC33CC">eoGenOp</font></b>,
and the test <b><tt><font color="#993300">_pop.exhausted()</font></tt></b>
will return false, so the <b><font color="#CC33CC">eoQuadOp</font></b>
will again be called. The second parent it needs will be given by a new
call to the embedded <b><font color="#009900">eoSelectOne</font></b> of
the&nbsp; and everything will go on smoothly, except that a total of 4
offspring will have been generated by application of this particular <b><font color="#CC33CC">eoSequentialOpContainer</font></b>.</li>
</ul>

<hr WIDTH="100%"><b><font color="#FF0000">TOC</font></b> : <a href="#introduction">Introduction</a>
<li>
if the argument is an <b><font color="#999900">eoSeqPopulator</font></b>,
the position of the iterator starts from the beginning of an existing population
(the source populations), and hence when an&nbsp; an <b><font color="#CC33CC">eoSequentialOpContainer</font></b>
is called, it goes through the whole remaining of the population (the test
<b><tt><font color="#993300">_pop.exhausted()</font></tt></b>
only returns true at end of the source population).</li>
<li>
From the above it is easy to see that passing an <b><font color="#999900">eoSeqPopulator</font></b>
to an <b><font color="#CC33CC">eoProportionalOpContainer</font></b> that
contains an <b><font color="#CC33CC">eoSequentialOpContainer</font></b>,
though not technically forbiddden, will most produce something&nbsp; totally
