Multi-armed bandit problems pertain to optimal sequential decision making and learning in unknown environments. Since the first bandit problem posed by Thompson in 1933 for the application of clinical trials, bandit problems have enjoyed lasting attention from multiple research communities and have found a wide range of applications across diverse domains. This book covers classic results and recent development on both Bayesian and frequentist bandit problems. We start in Chapter 1 with a brief overview on the history of bandit problems, contrasting the two schools—Bayesian and frequentist—of approaches and highlighting foundational results and key applications. Chapters 2 and 4 cover, respectively, the canonical Bayesian and frequentist bandit models. In Chapters 3 and 5, we discuss major variants of the canonical bandit models that lead to new directions, bring in new techniques, and broaden the applications of this classical problem. In Chapter 6, we present several representative application examples in communication networks and social-economic systems, aiming to illuminate the connections between the Bayesian and the frequentist formulations of bandit problems and how structural results pertaining to one may be leveraged to obtain solutions under the other.
Before she was ten years old, her every word and action had been taught by the king. After she was ten years old, her parents successively passed away, leaving only Chu Huainan as the disaster. She still remembered how her father trembled as he grabbed her hand before he died and summed up the words he had said from the bottom of his heart for the rest of his life. "After my son ascended the throne, there was something that I had no choice but to do." "This calamity Chu Huai Nan cannot be allowed to live." Chu Huai Nan was strong and influential. When the princess was young, he called himself the Regent, and he shamelessly made an imperial decree with a marriage contract to announce to the world. Thus, after the age of ten, Zhao's every word and action was not taught by the king. Instead, he would act as the son of the regent's adopted wife. Zhao He didn't want to do it, so on a dark and windy night, he directly ran away through his soul.

This book aims to provide readers with adequate knowledge for clinical application of Chinese medicine, which is in line with the fundamental principle of correspondence of Chinese medicinals and patterns. It contains a brief introduction to relative theories, divides these medicinals by actions into categories such as exterior-releasing, heat-clearing, purgative, dampness-dispelling, fluid retention-disinhibiting, interior-warming, qi-regulating, blood-invigorating, blood-stanching, food accumulation-relieving, phlegm, cough- and wheezing-arresting, mind-tranquilizing, liver-calming, orifices-opening, tonifying, astringing, and worm-dispelling, and elaborates each herb in terms of its actions, quality, indications, usage, and dosage. Furthermore, mnemonics and simple and effective formulas are included to help readers effectively grasp the concepts behind practical applications, and precautions and daily practices are specifically designed to support readers in easily understanding and retaining the information.

This book presents the latest progress in enhanced oil recovery technology and introduces the application of various enhanced oil recovery methods in oilfield development. Enhanced oil recovery (EOR) is a continuous theme in oilfield development. Due to the influence of geological conditions, development mode and physical and chemical factors, more than half of the proven oil reserves remain underground and cannot be accessed. Therefore, many enhanced oil recovery methods have been developed to achieve higher oil recovery. This book presents the basic principles and provides the chemistry knowledge related to enhanced oil recovery. It also expounds the applicable criteria of chemical agents. In addition, combined with field application examples, the limitations of existing enhanced oil recovery methods are analyzed, and the future development direction of enhanced oil recovery technology is highlighted. It is worth noting that the integral profile control and water shutoff technology in this book is widely recognized in the enhanced oil recovery industry and has achieved remarkable economic benefits. Given its scope, this book is useful for the scientific and technical personnel engaged in the study of oil recovery chemistry and enhanced oil recovery and also as a teaching reference for teachers and students majoring in petroleum engineering and oilfield chemistry.

Zhao Yan was a woman from the twenty-first century. As a modern person who believed in science and always spoke of it, Zhao Yan experienced something that no one believed in and could not accept. Moreover, after transmigrating, he had an exchange with another woman's soul, and this woman was very annoying to him. "Zhao Yan, who had just transmigrated over, got to know Xiao Wang, and even had a relationship with him. When a fire broke out on the day of their wedding, she swapped her soul with the Maidservant Chen Feng, who she had always hated. She changed into Chen Xiaolian Feng's appearance, and was saved by Zheng Hao.
The dramatic impact of low dimensional semiconductor structures on c- rent and future device applications cannot be overstated. Research over the last decade has highlighted the use of quantum engineering to achieve p- viously unknown limits for device performance in research laboratories. The modi?ed electronic structure of semiconductor quantum structures results in transport and optical properties, which di?er from those of constituent bulk materials. The possibility to tailor properties, such as bandgap, strain, band o?set etc. , of two-dimensional (2D) semiconductors, e. g. quantum wells, for speci?c purposes has had an extensive impact on the electronics, which has resulted in a dramatic renewal process. For instance, 2D structures are today used in a large number of high speed electronics and optoelectronic appli- tions (e. g. detectors, light emitting diodes, modulators, switches and lasers) and in daily life, in e. g. LED-based tra?c lights, CD-players, cash registers. The introduction of impurities, also in very small concentrations, in a semiconductor can change its optical and electrical properties entirely. This attribute of the semiconductor is utilized in the manifoldness of their app- cations. This fact constitutes the principal driving force for investigation of the properties of the impurities in semiconductors. While the impurities in bulk materials have been investigated for a long time, and their properties are fairly well established by now, the corresponding studies of impurities in quantum wells is a more recent research area.
Crossing through missions was difficult, so they thought it was a good opportunity for regeneration. Who would have thought that they would somehow become puppets in the hands of others? Stealing the Imperial Jade Seal? Stealing the information? His carelessness had provoked the prince who had an esteemed status that was as cold as ice and frost. With each blow, he would leap upwards, and the mouse would play with the kitten, smoothly placing the handsome guy into his bag. Love enemies, have fun all the way, love and hate, but life is just a hundred.
Performance evaluation of increasingly complex human-made systems requires the use of simulation models. However, these systems are difficult to describe and capture by succinct mathematical models. The purpose of this book is to address the difficulties of the optimization of complex systems via simulation models or other computation-intensive models involving possible stochastic effects and discrete choices. This book establishes distinct advantages of the "softer" ordinal approach for search-based type problems, analyzes its general properties, and shows the many orders of magnitude improvement in computational efficiency that is possible.
Once transmigrated, imprisoned, poisoned, she could not bear it any longer, she decided to kill; he, elegant, uninhibited, uninhibited, he had destroyed her family. lacked deep love for her, loved and hated her for her entanglement, he asked her to forgive him, she said yes, but you must give up your world!
Yang Jie secretly peeked at the village flowers as he changed his clothes. The village flowers were chasing after him, and by chance. he obtained a mysterious jade bottle. From then on, he was chased by even more beauties! "Big brother Yang, I want to give birth to a baby for you!" "Big brother Yang, I want to give birth to your little piglet ... ...
