subsequence的短语

subsequence的短语单词：subsequence1.1 词性：名词1.2 释义：随后；接着；后续；子序列（在数学或计算机科学等领域中，指序列中的一部分，其元素按原序列顺序排列）1.3 英文解释：A following part or sequence; in mathematics or computer science, a subset of a sequence where the elements are in the same order as in the original sequence.1.4 相关词汇：同义词有 sequel，succession；派生词有 subsequent（形容词，随后的；后来的）。

---2 起源与背景2.1 词源：源于拉丁语“sub-”（在……之下；低于；次于）和“sequi”（跟随），组合起来表示在某个序列之后的部分或跟随而来的情况。

2.2 趣闻：在一些古老的家族族谱记载中，会详细描述家族成员的出生顺序以及后续（subsequence）的重大事件，这些记录不仅是家族传承的一部分，也为研究当时的社会文化和人口发展提供了有价值的线索。

例如，通过分析不同家族的 subsequence 信息，可以了解到特定时期的婚姻习俗、寿命情况等。

---3 常用搭配与短语3.1 短语：- in subsequence：在随后；接下来。

例句：We will discuss the details in subsequence. 翻译：我们将在接下来讨论细节。

- subsequence of events：事件的后续发展。

Longest common subsequence

Lemma:
If I is an IS of π with length equal to the size of a cover C of π, then I is a LIS of π and C is the smallest cover of size c.
5
Proof
If I is an increasing sequence, it cannot contain more than one element from a decreasing sequence. This means that no increasing subsequence can have size more than the size of any cover C, that is, if a maximum of one element from each can participate in any increasing sequence. Thus, an IS derived from this decomposition can have a maximum length of |C |=c. Conversely, C must be the smallest. If not, let c’ be the length of a cover C’ such that |C’|=< c i.e., if we derive IS from C, it must contain more than one element from one of the decreasing sequence of C’, which is not possible. Hence C has to be of smallest size.

How I Can Help You
• If you have a question, you can ask me face-to-face
Prerequisite and Description
• Prerequisite: MATH 170 Calculus I and CSCI 185 Programming II • Description: An introduction to discrete structures with applications to computing problems. Topics include logic, sets, functions, relations, proof techniques and algorithmic analysis. Graph theory and trees may be studied as well
Course Objectives
1. Relate practical examples to the appropriate set, function, or relation model, and interpret the associated operations and terminology in context 2. Apply proof techniques, including logic, to problems 3. Differentiate between dependent and independent events 4. Apply the binomial theorem to independent events and Bayes’ theorem to dependent events, and solve problems such as Hashing 5. Relate ideas of mathematical induction(归纳) to recursion and apply it to problems in computer science setting 6. Apply the basic counting principles, permutations and combinations to problems in computer science setting 7. Implementing algorithms in C or C++ programs

离散数学课件(英文版)----Counting

• Is the set of rational numbers countable?
Set of Ordered Pairs
• The set of all objects with the form <i,j> is countable, where i,j are nonnegative integers.
Proof of Countability
• The set of all integers is countable.
– We can arrange all integer in a linear list as follows: 0,-1,1,-2,2,-3,3,... that is: positive k is the (2k+1)th element, and negative k is the 2kth element in the list.
– p(A) = 2n. Why?
• 加法原则
– 一件事情有两种做法，第一种做法有n种方式，第二种做法有m种方式，则完成这件事情共有m＋n种方法 – 定义标识符：由字符开头的8位字符数字串或者一位字符。共有多少个合法标识符？ – 含数字1的小于10000的正整数个数
Permutations
• Problem 1:
Countable Set
• A set A is countable if and only if we can arrange all of its elements in a linear list in a definite order.
– “Definite” means that we can specify the first, second, third element, and so on. – If the list ended and with the nth element as its last element, it is finite. – If the list goes on forever, it is infinite.

If “” is associative, then x1x2x3… xn can be computed by any order of among the (n-1) operations, with the constraint that the order of all operands are not changed.
If S has a left identity and a right identity as well, then they must be equal, and this element is also an identity of the system: e l = e l e r= e r If existing, the identity of an algebraic system is unique: e 1= e 1e 2= e 2

An example ({1,2},*), * defined as follows:
For any x,y∈{1,2}, x*y=y Proof: it should be proved that for any x,y,z in {1,2}, (x*y)*z = x* (y*z)

Example of Definite Integral Problems
Example (Area of a trapezoid with a curved top) Computing the area surrounded by the curve y f ( x)( f ( x) 0), the vertical lines x a, x b and the horizontal line y 0.
On each subinterval [xk1, xk ] , select arbitrarily a point k ,
xk1 k xk , and form the product:
f (k )xk , k 1, 2,L, n.
Add the n products f (k )xk to form the sum
integrand f and the interval of integration. Also, it is
independent of the variable of integration x . Hence the following
integrals are the same
