Game theory, alive by Anna R Karlin( Book )

13 editions published between 2016 and 2017 in English and held by 142 WorldCat member libraries worldwide

"This book presents a rigorous introduction to the mathematics of game theory without losing sight of the joy of the subject. This is done by focusing on theoretical highlights (e.g., at least six Nobel Prize winning results are developed from scratch) and by presenting exciting connections of game theory to other fields, such as computer science, economics, social choice, biology, and learning theory. Both classical topics, such as zero-sum games, and modern topics, such as sponsored search auctions, are covered. Along the way, beautiful mathematical tools used in game theory are introduced, including convexity, fixed-point theorems, and probabilistic arguments. The book is appropriate for a first course in game theory at either the undergraduate or graduate level, whether in mathematics, economics, computer science, or statistics."--Resource home page

Experience with a regular expression compiler by Anna R Karlin( Book )

3 editions published in 1983 in English and held by 10 WorldCat member libraries worldwide

The language of regular expressions is a useful one for specifying certain sequential processes at a very high level. They allow easy modification of designs for circuits, like controllers, that are described by patterns of events they must recognize and the responses they must make to those patterns. This paper discusses the compilation of such expressions into reasonably compact layouts. The translation of regular expressions into nondeterministic automata by two different methods is discussed, along with the advantages of each method. A major part of the compilation problem is selection of good state codes for the nondeterministic automata; one successful strategy is explained in the paper

Empirical studies of competitive spinning for shared-memory multiprocessors( Book )

1 edition published in 1991 in English and held by 3 WorldCat member libraries worldwide

Of particular interest are competitive strategies, for which the performance can be shown to be no worse than some constant factor times an optimal off-line strategy. The performance of five competitive strategies is compared with that of always blocking, always spinning, or using the optimal off-line algorithm. Measurements of lock-waiting time distributions for five parallel programs were used to compare the cost of synchronization under all the strategies. Additional measurements of elapsed time for some of the programs and strategies allowed assessment of the impact of synchronization strategy on overall program performance. Both types of measurements indicate that the standard blocking strategy performs poorly compared to mixed strategies
Information economics in the age of e-commerce : models and mechanisms for information-rich markets by L. Elisa Celis( )

1 edition published in 2012 in English and held by 3 WorldCat member libraries worldwide

The internet has dramatically changed the landscape of both markets and computation with the advent of electronic commerce (e-commerce). It has accelerated transactions, informed buyers, and allowed interactions to be computerized, enabling unprecedented sophistication and complexity. Since the environment consists of multiple owners of a wide variety of resources, it is a distributed problem where participants behave strategically and selfishly. This led to the birth of algorithmic game theory, whose goal is to understand equilibria arising in these strategic environments, study their computational complexity, and design mechanisms accordingly. More recently, the prevalence and access to information about consumers and products has increased dramatically and changed the landscape accordingly. In this thesis I focus on two simple yet fundamental observations which require further investigation as the field of algorithmic game theory progresses in the context of information economics. Specifically: 1) Access to information widens an agent's strategy space, and 2) the generation and exchange of information between agents is itself a game. There are three specific problems we address in this thesis. Informed Valuations: Increasingly sophisticated consumer tracking technology gives advertisers a wealth of information which they use to reach narrowly targeted consumer demographics. With targeting, advertisers are able to bid differently depending on the age, location, computer, or even browsing history of the person viewing a website. This is preferable to bidding a fixed value since they can choose to only bid on consumers who are more likely to be interested in their product. This results in an increase in revenue to the advertiser. Notice, however, that this implies information has changed the distribution of bids. With this change, common assumptions, which are reasonable in the absence of information, no longer hold. Thus, the mechanisms currently in place are no longer optimal. Using historical bidding data from a large premium advertising exchange, we show that the bidding distributions are unfavorable to the standard mechanisms. This motivates our new BIN-TAC mechanism, which is simple and effective in extracting revenue in the presence of targeting information. Bidders can "buy-it-now", or alternatively "take-a-chance" in an auction, where the top d> 1 bidders are equally likely to win. The randomized take-a-chance allocation incentivizes high valuation bidders to buy-it-now. We show that for a large class of distributions, this mechanism outperforms the second-price auction, and achieves revenue performance close to Myerson's optimal mechanism. We apply structural methods to our data to estimate counterfactual revenues, and find that our BIN-TAC mechanism improves revenue by 4.5% relative to a second-price auction with optimal reserve. Information Acquisition: A prevalent assumption in traditional mechanism design is that the buyers know their precise value for an item; however, this assumption is rarely accurate in practice. Judging the value of a good is difficult since it may depend on many unknown parameters such as the intrinsic quality of the good, the saving it will yield in the future, or the buyer's emotional state. Additionally, the estimated value for a good is not static; buyers can "deliberate", i.e. spend money or time, in order to refine their estimates by acquiring additional information. This information, however, comes at some cost, either financial, computational or emotional. It is known that when deliberative agents participate in traditional auctions, surprising and often undesirable outcomes can occur. We consider optimal dominant strategy mechanisms for one-step deliberative setting where each user can determine their exact value for a fixed cost. We show that for single-item auctions under mild assumptions these are equivalent to a sequential posted price mechanism. Additionally, we propose a new approach that allows us to leverage classical revenue-maximization results in deliberative environments. In particular, we use Myerson (1981) to construct the first non-trivial (i.e., dependent on deliberation costs) upper bound on revenue in deliberative auctions. This bound allows us to apply existing results in the classical environment to a deliberative environment; specifically, for single-parameter matroid settings, sequential posted pricing is a 2-approximation or better. Exchange Networks: Information is constantly being exchanged in many forms; i.e. communication among friends, company mergers and partnerships, and more recently, selling of user information by companies such as BlueKai. Exchange markets capture the trade of information between agents for profit, and we wish to understand how these trades are agreed upon. Understanding information markets helps us determine the power and influence structure of the network. To do this, we consider a very general network model where nodes are people or companies, and weighted edges represent profitable potential exchanges of information, or any other good. Each node is capable of finalizing an exactly one of its possible transactions; this models the situation where some form of exclusivity is involved in the transaction. This model is in fact very general, and can capture everything from targeting information exchange to the marriage market. A balanced outcome in an exchange network is an equilibrium concept that combines notions of stability and fairness. In a recent paper, Kleinberg and Tardos introduced balanced outcomes to the computer science community and provided a polynomial time algorithm to compute the set of such outcomes. Their work left open a pertinent question: are there natural, local dynamics that converge to a balanced outcome? We answer this question in the affirmative by describing such a process on general weighted graphs, and show that it converges to a balanced outcome whenever one exists. In addition, we present a new technique for analyzing the rate of convergence of local dynamics in bargaining networks. The technique reduces balancing in a bargaining network to optimal play in a random-turn game, and allows a tight polynomial bound on the rate of convergence for a nontrivial class of unweighted graphs

Energy-aware batch scheduling by Jessica Chang( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

The subject of this thesis concerns algorithmic aspects of energy-related trends in computation. Within recent years, the computationally heaviest jobs are executed over massive corpora residing at data centers, whose energy profiles differ from those of standard desktops, and whose power consumption translates into an operational budget on the order of millions of dollars. Designing schedules to optimize notions of power consumption is sometimes at odds with standard techniques prevalent in the classical scheduling theory, which has traditionally focused on objectives capturing the interests of the scheduler (e.g., makespan) or of individual jobs (e.g., flow time). Thus, we study a fairly simple model of energy usage: the active time scheduling model. Formally, we are interested in scheduling a set of n jobs, each with release time, deadline and processing requirement, on a system comprised of a single batch machine, with batch parameter B. (The machine can be working on up to B jobs at the same time.) The cost of a schedule is simply the amount of time that the system, i.e., the machine, is working. This is akin to the magnitude of the schedule's projection onto the time axis. The underlying assumption is that the cost for the machine to be active is roughly the same, regardless of whether it is working on only one job or operating at full capacity. We give a fast algorithm for the basic case in which jobs are unit length and time is slotted. When time is not slotted, the problem still admits a polynomial-time solution, albeit of higher time complexity, via dynamic programming techniques. On the other hand, when time is slotted, but jobs may have multiple feasible intervals, the problem is NP-hard for B > 2, and otherwise can be solved via b-matching techniques. When jobs are arbitrary in length and can be preempted, but have a single feasible interval, we also show that a large class of algorithms is 5-approximate. We also empirically compare algorithms within this class with the incumbent greedy algorithm due to Wolsey; the latter algorithm is widely implemented in practice. This comparison is cast within a framework general enough to capture other canonical covering problems, most notably Capacitated Set Cover. In particular, we design a heuristic LPO that essentially complements Wolsey's algorithm and propose optimizations to both approaches. At a high level, our findings solidly establish LPO as a competitive, if not superior, alternative to Wolsey's algorithm, with respect to both solution quality and number of subroutine calls made. Finally, this thesis makes theoretical headway on the well-studied busy time problem. The key assumption that sets this apart from the aforementioned active time problem is that under the busy time model, the system has access to an unlimited number of identical batch machines. For non-preemptive jobs of arbitrary length, we give a 3-approximation that leverages important insights for the special case where the instance consists of interval jobs. When preemption is permitted, we give an exact algorithm for unbounded B; this result yields a simple 2-approximation for bounded B
On best-response bidding in GSP auctions by Matthew Cary( Book )

3 editions published in 2008 in English and held by 1 WorldCat member library worldwide

How should players bid in keyword auctions such as those used by Google, Yahoo! and MSN? We model ad auctions as a dynamic game of incomplete information, so we can study the convergence and robustness properties of various strategies. In particular, we consider best-response bidding strategies for a repeated auction on a single keyword, where in each round, each player chooses some optimal bid for the next round, assuming that the other players merely repeat their previous bids. We focus on a strategy we call Balanced Bidding (bb). If all players use the bb strategy, we show that bids converge to a bid vector that obtains in a complete information static model proposed by Edelman, Ostrovsky and Schwarz (2007). We prove that convergence occurs with probability 1, and we compute the expected time until convergence
