7 upwards

10 use Math::NumSeq::GolombSequence;
11 my $seq = Math::NumSeq::GolombSequence->new;
12 my ($i, $value) = $seq->next;
13
15 A sequence of integers with each run length being given by the sequence
16 itself.
17
18 1, 2,2, 3,3, 4,4,4, 5,5,5, 6,6,6,6,...
19
20 Starting from 1,2, at i=2 the value is 2, so there should be a run of
21 two 2s. Then at i=3 value 2 means two 3s. Then at i=4 value 3 means a
22 run of three 4s, and so on.
23
24 Values Run Length (is the sequence itself)
25 1, 1
26 2,2, 2
27 3,3, 2
28 4,4,4, 3
29 5,5,5, 3
30 6,6,6,6, 4
31 ... ...
32
33 Using Values
34 The default is to use all integers successively for the values. The
35 "using_values" option can choose a different set of values. In each
36 case those values from the sequence are the run lengths.
37
38 "using_values => 'odd'" uses only odd numbers,
39
40 1, 3,3,3, 5,5,5, 7,7,7, 9,9,9,9,9, ...
41
42 "using_values => 'even'" uses only even numbers,
43
44 2,2, 4,4, 6,6,6,6, 8,8,8,8, ...
45
46 "using_values => '3k'" uses only triples,
47
48 3,3,3, 6,6,6, 9,9,9, 12,12,12,12,12,12, ...
49
50 "using_values => 'squares'" uses the squares,
51
52 1, 4,4,4,4, 9,9,9,9, 16,16,16,16, 25,25,25,25, ...
53
54 "using_values => 'primes'" uses the primes,
55
56 2,2, 3,3, 5,5,5, 7,7,7, 11,11,11,11,11, ...
57
59 See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence
60 classes.
61
62 "$seq = Math::NumSeq::GolombSequence->new ()"
63 "$seq = Math::NumSeq::GolombSequence->new (using_values => $str)"
64 Create and return a new sequence object. The "using_values" option
65 as described above can be
66
67 "all"
68 "odd"
69 "even"
70 "3k"
71 "squares"
72 "primes"
