The pen has strict criteria for the classification given in the preceding, therefore, the next key question is how to divide the segment. Now, given by a similar pen, but a significant difference between the criteria for the classification. Representative of the pen up with S, X on behalf of the pen down. Then all the segments, no more than two kinds: one, from start up pen; Second, start from the pen down. Simplicity, in order to line up the pen as an example the beginning of that classification standards.
to start up the pen line, the sequence can use a pen, said: S1X1S2X2S3X3 ... SnXn. Easy to prove that any between Si and Si +1, there must be overlap interval. The inspection sequence X1X2 ... Xn, the sequence, Xi and Xi +1 is not necessarily a coincidence between the interval, so this series is more representative of the nature of the line.
Definition: sequence X1X2 ... Xn into a line up the pen began to feature sequence; sequence S1S2 ... Sn into a line down the pen began to feature sequence. Characteristics of the two sequences do not overlap interval between adjacent elements, known as a gap in the sequence.

on the characteristic sequence, to each element as a K line, then, as if looking for map K line type of approach, there are also so-called inclusion relation, can also conduct a non-included treatment. After dealing with the characteristics of non-containing sequence, a standard feature of sequence. There will be no special instructions, refer to the standard sequences are characteristic features of sequences.
(this figure relics from the pink blog)
reference chart on the top of the general K Classification and definition of the end of typing, you can determine the sequence characteristics of top and bottom. Note that in order to start up the pen features a line sequence, only the top classification study; to start down the pen line, only to examine the end of typing.
standard feature in the sequence, constitute the type of the three adjacent elements, only two possibilities:
the first case:
top characteristic sequence typing,
ralph lauren sale, the first and the second element does not exist between the characteristic sequence of the gap, then the line type in the top end of the high points, the high end of the line; characteristic sequence bottom type, the first and the second element does not exist between the characteristic sequence of the gap, then the line type in the low end at the end, the low end of the line;
second situation:
characteristic sequence of the top sub-type, the first and the second element of the gap between the characteristic sequence,
ralph lauren polo, from the highest point on the classification of the beginning of the sequence down the characteristics of a sequence appears at the end type, then the Typing in the top line of high end point, the high end of the line; the end of the sequence characteristics of type, the first and the second element of the gap between the characteristic sequence, from the lowest point on the classification The start up sequence features a series tops and type, then the line type in the low end at the end, the low end of the line;
(string of prayer beads from the above two graphs Wu wrapped around the blog)
stressed in the second case, the latter characteristic sequence is not necessarily a characteristic sequence before the closure of the corresponding gap, and the second sequence type, regardless of the first two cases, as long as partakers type can.
the above two cases, on the line given by all standards. Obviously, there characteristic sequence typing is a prerequisite for the end line. This course is put in front of Therefore, after the division on the line,
ralph lauren uk, are the basis of this precise definition.
this definition is a bit complicated to figure out features of the first sequence of first, and then find out the standard features of sequence, then the top of the standard features of the sequence type classification and the bottom. The type Youyi type elements and the second element of the first if there are gaps between the two types of situation. Must take this logic to figure out, or will faint.
Obviously, according to this division, all at the same level trend map can be uniquely divided into segments of the connection, all at the same level as the trend graph can be uniquely connected by the pen. With these two basic, then the entire central nervous system and the trend of the type of recursion can be established. This is the basic foundation, be sure to find out, or certainly not learn.
Finally, try to draw points chart for you to distinguish some of the above concepts, it is best to look at the definition, this is the real understanding is only a secondary figure. Winning the first two out of the line graphics division.

line damage and that is the two cases. Also included in the second case in which one of the most special, so-called small-level to turn up the level even after the characteristics of the final sequence of the gap are not covering the situation.
In fact, the logic of things are best learned, the key is to start from the basic concept, and then string together the whole logic, so that a pass Belden. Otherwise, the only hell broke loose.
problem for the stone monkey friends, as a representative, say a few words more;
document destruction and line damage, because the two are mutually contained in the concept. Damage to a certain segment is not the document destruction, nor is it sure to document destruction of damaged line.
Clearly, the online section of the first case, destruction, must be the document destruction.
line segments damaged the second case, not unilaterally.
the other hand, line damage, if not document destruction,

So why document destruction singled out? Because there are dynamics on the significance of document destruction.
the ID theory, and physics is somewhat similar to some, is to explore the dynamics of things, in this regard,
ralph lauren shop, you are the greatest exposure is the divergence,

with pen, then the line is very simple, the line at least There are three pens, no more than two segments, from a start up, and down from a start.
up for a beginning from which the sequence of this type pose: d1g1d2g2d3g3 ... dngn (on behalf of one of the first i-end di, gi, on behalf of i-top). If you find i and j, j> = i +2, so dj <= gi, then called up the line to be document destruction.
Block Music Mentor:
find i and j
j> = i +2 What does that mean???
======================
Here are my answers.
Figure I: a damaged segment

as this is a typical example, where 3> = 1 +2 make d3 = 5 +2 makes d8 <g5, called g6-d8 damage to this segment of the d5-g6 this segment.
line segment is the most extreme damage is a destruction of such a situation is shown in Figure I. This is j = i +2, only possible dj <= gi situation.
and if j = i +1, it must have dj <gi that di +1 <gi, it is clear that a bound digi with (di +1- gi +1) that a coincidence, this fundamental impossible line damage.
and Figure II is the destruction of line segments, it is clear that this necessarily j> i +2.
such a destruction of line segments and line segments in both cases damage to form a line on the destruction of all the circumstances, so only line up to be pen destroyed.
the above two diagrams to explain what it meant to line damage. This segment has been damaged people understand the very simple, I hope to be writing for the definition of confusion can be helpful for beginners.
need to affirm that, Figure I and II only to explain the destruction of the painting line, where only consider the problem of damage regardless of line segments set up other conditions, if strict accordance with the segment by definition, the above Both plans are imprecise.
In fact, if the above two diagrams used as a division of the popular segment, then one is an unfinished map map, can not determine a period or two, while the second is simply a line graph only.
the two plans to do the following changes:

done it after the first two plans, Figure II is three paragraphs.
