In a probabilistic model, a rare event is an event with a very small probability of occurrence. The forecasting of rare events is a formidable task but is important in many areas. For instance a catastrophic failure in a transport system or in a nuclear power plant, the failure of an information processing system in a bank, or in the communication network of a group of banks, leading to financial losses. Being able to evaluate the probability of rare events is therefore a critical issue.

Monte Carlo Methods, the simulation of corresponding models, are used to analyze rare events. This book sets out to present the mathematical tools available for the efficient simulation of rare events. Importance sampling and splitting are presented along with an exposition of how to apply these tools to a variety of fields ranging from performance and dependability evaluation of complex systems, typically in computer science or in telecommunications, to chemical reaction analysis in biology or particle transport in physics.

Graduate students, researchers and practitioners who wish to learn and apply rare event simulation techniques will find this book beneficial.

This book constitutes the refereed proceedings of the 18th International Conference on Economics of Grids, Clouds, Systems, and Services, GECON 2021, in September 2021. Due to COVID-19 pandemic the conference was held virtually hosted by the Libera Università Maria SS. Assunta (LUMSA), Rome, Italy.

This book discusses the pros and cons of information and communication (ICT) neutrality. It tries to be as objective as possible from arguments of proponents and opponents, this way enabling readers to build their own opinion. It presents the history of the ongoing network neutrality debate, the various concepts it encompasses, and also some mathematical developments illustrating optimal strategies and potential counter-intuitive results, then extends the discussion to connected ICT domains. The book thus touches issues related to history, economics, law, networking, and mathematics.

After an introductory chapter on the history of the topic, chapter 2 surveys and compares the various laws in place worldwide and discusses some implications of heterogeneous rules in several regions. Next, chapter 3 details the arguments put forward by the participants of the net neutrality debate. Chapter 4 then presents how the impact of neutral or non-neutral behaviors can be analyzed mathematically, with sometimes counter-intuitive results, and emphasizes the interest of modeling to avoid bad decisions. Chapter 5 illustrates that content providers may not always be on the pro-neutrality side, as there are situations where they may have an economic advantage with a non-neutral situation, e.g. when they are leaders on a market and create barriers to entry for competitors. Another related issue is covered in chapter 6, which discusses existing ways for ISPs to circumvent the packet-based rules and behave non-neutral without breaking the written law. Chapter 7 gives more insight on the role and possible non-neutral behavior of search engines, leading to another debate called the search neutrality debate. Chapter 8 focuses on e-commerce platforms and social networks, and investigates how they can influence users’ actions and opinions. The issue is linked to the debate on the transparency of algorithms which is active in Europe especially. Chapter 9 focuses on enforcing neutrality in practice through measurements: indeed, setting rules requires monitoring the activity of ICT actors in order to sanction non-appropriate behaviors and be proactive against new conducts. The chapter explains why this is challenging and what tools are currently available. Eventually, Chapter 10 briefly concludes the presentation and opens the debate.

This book constitutes the proceedings of the 11th International Conference on Network Games, Control and Optimization 2024, NETGCOOP 2024, held during October 9-11, 2024, in Lille, France.

The 13 full papers and 1 short paper were carefully reviewed and selected from 21 submissions. The papers are organized in the following topical sections: Scheduling, Queuing Systems & Resource Allocation; Modeling & Performance; Pricing & Economic Models; and Energy, Generative AI.
