14	* FloatVectorSpecies is a subclass of VectorSpecies with special
15	* constraints for floating-point vectors, namely FloatVectorIndividual and
16	* DoubleVectorIndividual.
17	*
18	* <p>FloatVectorSpecies can specify min/max numeric constraints on gene values
19	* in three different ways.
20	*
21	* <ol>
22	* <li> You may provide a default min and max value.
23	* This is done by specifying:
24	* <p><i>base</i>.<tt>min-gene</tt>
25	* <br><i>base</i>.<tt>max-gene</tt>
26	* <p><i>Note:</i> you <b>must</b> provide these values even if you don't use them,
27	* as they're used as defaults by #2 and #3 below.
28	*<p>
29	* <li> You may provide min and max values for genes in segments (regions) along
30	* the genome. This is done by specifying:
31	* <p><i>base</i>.<tt>num-segments</tt>
32	* The segments may be defined by either start or end indices of genes.
33	* This is controlled by specifying the value of:
34	* <p><i>base</i>.<tt>segment-type</tt>
35	* which can assume the value of start or end, with start being the default.
36	* The indices are defined using Java array style, i.e. the first gene has the index of 0,
37	* and the last gene has the index of genome-size - 1.
38	* <p>Using this method, each segment is specified by<i>j</i>...
39	* <p><i>base</i>.<tt>segment.</tt><i>j</i><tt>.start</tt>
40	* <br><i>base</i>.<tt>segment.</tt><i>j</i><tt>.min-gene</tt>
41	* <br><i>base</i>.<tt>segment.</tt><i>j</i><tt>.max-gene</tt>
42	* if segment-type value was chosen as start or by:
43	* <p><i>base</i>.<tt>segment.</tt><i>j</i><tt>.end</tt>
44	* <br><i>base</i>.<tt>segment.</tt><i>j</i><tt>.min-gene</tt>
45	* <br><i>base</i>.<tt>segment.</tt><i>j</i><tt>.max-gene</tt>
46	* if segment-type value is equal to end.
47	*<p>
48	* <li> You may provide min and max values for each separate gene.
49	* This is done by specifying (for each gene location <i>i</i> you wish to specify)
50	* <p><i>base</i>.<tt>min-gene</tt>.<i>i</i>
51	* <br><i>basn</i>.<tt>max-gene</tt>.<i>i</i>
52	* </ol>
53	*
54	* <p>Any settings for #3 override #2, and both override #1.
55	*
56	* <p>
57	* FloatVectorSpecies provides support for three ways of mutating a gene:
58	* <ul>
59	* <li>replacing the gene's value with a value uniformly-drawn from the gene's
60	* range (the default behavior, legacy from the previous versions).</li>
61	* <li>perturbing the gene's value with gaussian noise; if the gene-by-gene range
62	* is used, than the standard deviation is scaled to reflect each gene's range.
63	* If the gaussian mutation's standard deviation is too large for the range,
64	* than there's a large probability the mutated value will land outside range.
65	* We will try again a number of times (100) before giving up and using the
66	* previous mutation method.</li>
67	* <li>perturbing the gene's value with noise chosen from a <i>polynomial distribution</i>,
68	* similar to the gaussian distribution. The polynomial distribution was popularized
69	* by Kalyanmoy Deb and is found in many of his publications (see http://www.iitk.ac.in/kangal/deb.shtml).
70	* The polynomial distribution has two options. First, there is the <i>index</i>. This
71	* variable defines the shape of the distribution and is in some sense the equivalent of the
72	* standard deviation in the gaussian distribution. The index is an integer. If it is zero,
73	* the polynomial distribution is simply the uniform distribution from [1,-1]. If it is 1, the
74	* polynomial distribution is basically a triangular distribution from [1,-1] peaking at 0. If
75	* it is 2, the polynomial distribution follows a squared function, again peaking at 0. Larger
76	* values result in even more peaking and narrowness. The default values used in nearly all of
77	* the NSGA-II and Deb work is 20. Second, there is whether or not the value is intended for
78	* <i>bounded</i> genes. The default polynomial distribution is used when we assume the gene can
79	* take on literally any value, even beyond the min and max values. For genes which are restricted
80	* to be between min and max, there is an alternative version of the polynomial distribution, used by
81	* Deb's team but not discussed much in the literature, desiged for that situation. We assume boundedness
82	* by default, and have found it to be somewhat better for NSGA-II and SPEA2 problems. For a description
83	* of this alternative version, see "A Niched-Penalty Approach for Constraint Handling in Genetic Algorithms"
84	* by Kalyanmoy Deb and Samir Agrawal. Deb's default implementation bounds the result to min or max;
85	* instead ECJ's implementation of the polynomial distribution retries until it finds a legal value. This
86	* will be just fine for ranges like [0,1], but for smaller ranges you may be waiting a long time.
87	* </ul>
