选择题英语作文Multiple choice questions have long been a staple of academic assessments, from standardized tests to classroom exams. These types of questions, which present a set of options for the test-taker to choose from, offer a number of advantages over other assessment formats. However, they also have certain limitations that are important to consider. In this essay, we will explore the benefits and drawbacks of multiple choice questions, and discuss the role they play in evaluating student learning.One of the primary advantages of multiple choice questions is their objectivity. Unlike open-ended or essay-style questions, which can be subject to subjective interpretation by the grader, multiple choice questions have a clear and unambiguous correct answer. This makes them ideal for large-scale assessments, where consistency and fairness are paramount. The scoring process is also highly efficient, as multiple choice responses can be quickly and easily evaluated, either by hand or through automated scoring systems.Another key benefit of multiple choice questions is their ability tocover a broad range of content in a relatively concise format. By presenting a set of options, these questions can assess a student's knowledge of a wide variety of topics or concepts, without requiring lengthy written responses. This makes them well-suited for exams that need to cover a significant amount of material in a limited amount of time, such as standardized tests or final exams.Furthermore, multiple choice questions can be designed to test a variety of cognitive skills, from simple recall of factual information to more complex problem-solving and critical thinking abilities. By carefully crafting the question stem and the response options, instructors can create multiple choice items that assess a range of learning objectives, from basic comprehension to higher-order thinking.However, multiple choice questions also have some limitations that are important to consider. One of the primary criticisms is that they can encourage a "guessing" mentality, where students attempt to identify the correct answer through process of elimination, rather than demonstrating a deep understanding of the material. This can be particularly problematic in situations where the stakes are high, such as high-stakes standardized tests, as it can lead to inflated scores that do not accurately reflect a student's true knowledge and abilities.Another potential drawback of multiple choice questions is their inability to assess certain types of skills, such as written communication, problem-solving, or creative thinking. These skills are often better evaluated through open-ended or performance-based assessments, where students have the opportunity to demonstrate their abilities in a more authentic and comprehensive manner.Additionally, the construction of effective multiple choice questions can be challenging, requiring careful attention to the wording of the question stem and the response options. Poorly designed multiple choice items can be confusing or ambiguous, leading to inaccurate assessments of student learning.Despite these limitations, multiple choice questions continue to play a significant role in academic assessment, and they are likely to remain a prominent feature of many educational contexts. However, it is important for instructors and test developers to use these types of questions judiciously and in conjunction with other assessment methods, in order to provide a comprehensive and accurate evaluation of student learning.In conclusion, multiple choice questions offer a number of advantages, including objectivity, efficiency, and the ability to assess a broad range of content and cognitive skills. However, they alsohave certain limitations, such as the potential for guessing, the inability to assess certain types of skills, and the challenge of creating effective question items. By understanding both the benefits and drawbacks of multiple choice questions, educators can make informed decisions about how to best utilize them as part of a comprehensive assessment strategy.。

Dynamic topology:As the channel of communicationchanges, some of the neighbors who were reachable on theprevious channel might not be reachable on the currentchannel and vice versa. As a result the topology of the network changes with the change in frequency of operation resulting in route failures and packet loss.Heterogeneity:Different channels may support differenttransmission ranges, data rates and delay characteristics.Spectrum-Handoff delay:For each transition from onechannel to another channel due to the PU’s activity, thereis a delay involved in the transition called Spectrum- Handoff delay.All these factors decrease the predictability of the cause oftransit-delay and subsequent packet loss on the network. Thetime latency during channel hand-off in cognitive networksmight cause the TCP round trip timer to time out. TCP willwrongly recognize the delays and losses due to the abovefactors as network congestion and immediately take steps toreduce the congestion window size knowing not the cause ofpacket delay. This reduces the efficiency of the protocol insuch environments.动态技术:随着信道通信的变化,一些邻进信道的用户在原信道没有发生变化而在新信道发生变化,或者相反。

这部分内容大部分来自第四章,但是我根据自己的理解加上了其他的内容。

1.改良Experience replay buffer1.1 传统的Single-agent场景之下的Replay bufferReplay Buffer[90, 89]自从被提出后就成了Single-Agent强化学习的常规操作,特别是DQN一炮走红之后[72] 。

不过,Replay Buffer有着很强的理论假设,用原作者的话说是——The environment should not changeover time because this makes pastexperiences irrelevantor even harmful.(环境不应随时间而改变,因为这会使过去的experience replay变得无关紧要甚至有害)Replay buffer假设环境是stationary的,如果当前的环境信息不同于过去的环境信息,那么就无法从过去环境的replay中学到有价值的经验。

(画外音:大人,时代变了……别刻舟求剑了)在multi-agent场景下,每个agent都可以把其他的agent当作环境的一部分。

因为其他的agent不断地学习进化,所以agent所处的环境也是在不断变换的,也就是所谓的non-stationary。

因为multi-agent场景不符合replay buffer的理论假设,所以有的人就直接放弃治疗了——例如2016年发表的大名鼎鼎的RIAL和DIAL中就没有使用replay buffer。

of n variables yi = fn(i)(x1 , x2 , …, xn), i = 1, 2, ..., m (3) or y = F(x) in vector notation. Alternative implicit description is based on the so called output characteristic function (CF) [7] φ0 (x, y) = 1. (4) Machine representation of Boolean functions uses binary decision diagrams (BDDs), which can have many forms. Bit-level binary decision diagrams (BDDs), ordered binary decision diagrams (OBDDs) and reduced ordered binary decision diagrams (ROBDDs) are well known representation of a single Boolean function in a form of a directed acyclic graph [1]. Whereas ROBDD is a canonical (unique) representation for any given complete function and an order of variables, incomplete Boolean functions may be transformed into more than one complete form and into the associated ROBDD. Important parameters of a BDD are its size and width, i.e. the total number of decision nodes and the maximum number of edges between adjacent levels, where the edges pointing to the same nodes are counted as one. The size determines the memory space needed to store the BDD data structure while thees a BDD form factor since the height is given by the number of variables. The construction of minimum-size or by the same token minimum-width ROBDDs belong among NP-complete problems [5]; the size and width of the ROBDD depend on variable ordering and there are n! possible orderings of n variables. A heuristic approach can be used in a search for near-optimal orderings [6]. Upper bounds on the OBDD’s size and width for general random complete Boolean functions grow exponentially with number of variables n for any ordering, but functions used in digital systems design with few exceptions do have a reasonable BDD size and small width. M-ary decision diagrams are straightforward generalization of BDDs. They have two types of nodes: decision and terminal nodes. Decision node L is testing M-ary variable var(L) and its outgoing edges are marked by its values 0, 1, …, M-1. The terminal node assigns a single value from ZM (generally ZR, R≠M) to output y = Fn(x1, x2,…, xn). To represent a system of Boolean functions (1) by means of decision diagrams, we can use either m bit-level BDDs, one for each of m Boolean functions (possibly sharing some of their sub-diagrams in Shared BDDs or SBDDs, [7]), or one word-level BDD (WLBDD) with n Boolean decision variables and with R integer terminal values. There are many types of WLDDs. Multi-terminal BDDs have integer leaves and therefore represent functions from Booleans to integers. A BMD (Binary Moment Diagram) is more compact representation for some useful arithmetic functions which have exponential size if represented by MTBDDs. Hybrid decision diagrams HDDs are a combination of MTBDDs and BMDs. BDD for Characteristic Function (BDD for CF) [7] is yet another representation of multiple-output functions, which uses the shortest encoding of output vectors y by
I. INTRODUCTION Efficient evaluation of Boolean functions is an important part of many embedded software systems. Functions most frequently used in embedded system practice are not random, but application-specific with low complexity. Among them sparse functions defined below include applications such as encryption, data compression and conversion, pattern matching and searching, moving window functions on data streams, etc. We will address Boolean functions of large numbers (tens, hundreds) of variables because small size systems can be implemented directly in hardware, e.g. in PLA, ROM or TCAM (Ternary Content Addressable Memory). Software implementation of Boolean functions will be assumed in a form of a data structure describing the function and of a compiled program that reads the input vector and evaluates the function with the use of this data structure. The size of the code and of the data structure is one figure of merit and the other is the evaluation time from reading the input to generating the output. Hereafter we will use three compact representations: a PLA-like table, Look-Up Tables (LUTs) and binary decision diagrams (BDDs). The BDDs are well known, especially the reduced ordered BDDs (ROBDDs), [1]. On
