Reliable performance evaluations require the use of representative workloads. This is no easy task since modern computer systems and their workloads are complex, with many interrelated attributes and complicated structures. Experts often use sophisticated mathematics to analyze and describe workload models, making these models difficult for practitioners to grasp. This book aims to close this gap by emphasizing the intuition and the reasoning behind the definitions and derivations related to the workload models. It provides numerous examples from real production systems, with hundreds of graphs. Using this book, readers will be able to analyze collected workload data and clean it if necessary, derive statistical models that include skewed marginal distributions and correlations, and consider the need for generative models and feedback from the system. The descriptive statistics techniques covered are also useful for other domains.

“…Chess is not the only game plagued by bots, however. These technology cheats are very common in online games today, from traditional games such as poker and chess, all the way up to complex Massively Multiplayer Online Roleplaying Games (MMORPGs) like Blizzard Entertainment's World of Warcraft [5]. Keeping bots from ruining the game for honest players requires a constant effort, since whenever a game update to eliminate bots is implemented, the bot creators update their bot to circumvent the latest fix [6].…”

Cheating in chess can take many forms and has existed almost as long as the game itself. The advent of computers has introduced a new form of cheating into the game. Thanks to the computational power of modern-day computers, a player can use a program to calculate thousands of moves for him or her, and determine the best possible scenario for each move and countermove. These programs are often referred to as "bots," and can even play the game without any user interaction. In this paper, we describe a methodology aimed at preventing bots from participating in online chess games. The proposed approach is based on the integration of a CAPTCHA protocol into a game scenario, and the subsequent inability of bots to accurately track the game states. This is achieved by rotating the images of the individual chess pieces and adjusting their resolution in an attempt to render them unreadable by a bot. Feedback from users during testing shows that there is minimal impact on their ability to play the game. Players rated the difficulty of reading the pieces on a scale of one to ten, with an average rank of 6.5. However, the average number of moves to adjust to the distorted pieces was only 3.75. This tells us that, although it is difficult to read the pieces at first, it is easy to adjust quickly to the new image.

“…This particular type of online games is typically subscription based and players have to pay a monthly subscription fee in order to enjoy the online game services. It has been reported the subscriptions for one of the most popular MMOGs, World of Warcraft [2] has surpassed 11.5 million subscribers in 2008, with an estimated US$150 million in monthly subscription fees [3].…”

“…In the gaming community, the process of killing large numbers of enemies to gain experience points and to earn gold is known as 'farming' [3]. It has been estimated that a large portion of the number of subscription in the MMOG, World of Warcraft, can actually be attributed to farmers rather than genuine players [1].…”

Botting or automated programs in Massively Multiplayer Online Games (MMOGs) has long been a problem in these networked virtual environments. The use of bots gives cheating players an unfair advantage over other honest players. Using bots, players can potentially amass a huge amount of game wealth, resources, experience points, etc. without much effort, as bot programs can be run continuously for countless hours and will never get tired. Honest players on the other hand have to spend much more time and effort in order to gather an equal amount of game resources. This destroys the fun for legitimate players, ruins the balance of the game and threatens the game developer's revenue base as discontented players may stop playing the game. Research efforts have proposed the incorporation of CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) challenges in games to prevent or detect potential cheaters, by presenting challenges that are easy for a human to solve but are difficult for a computer to solve. However, the incorporation of CAPTCHA challenges in games is often seen in a negative light, as they are deemed to be intrusive and that they destroy the sense of immersion in the game. This research presents an approach of using CAPTCHAs in MMOGs that is both secure and adds gameplay value to the game.
