RESIM 2018:
12th International Workshop on Rare-Event Simulation

KTH Royal Institute of Technology
August 29-31, 2018


Organizers: Henrik Hult (KTH), Pierre Nyquist (TU/e)



RESIM 2018 will be the 12th workshop in a series of successful events held on the topic of rare-event simulation since 1997. The topics of the workshop covers all aspects of rare-event simulation, from purely theoretical developments to practical applications. The objective is to bring together researchers, not only from the mathematical sciences, and practitioners to discuss recent results and how methods and open problems from different areas can lead to new directions that drive the field forward.

Because of the interdisciplinary nature of the topic, a goal of the workshop is to enhance the interaction between experts in theoretical developments on the one hand, and experts from different application areas on the other. This will be reflected in the plenary talks as well as the invited and contributed sessions, where the aim is to have as diverse a program as possible.

The following is a snippet of the topics of the workshop:


Importance sampling
Averaging techniques
Cross-Entropy method
Large deviations theory
Interacting particles
Hybrid analytic/simulation techniques

Applications and models:

Queueing models
Reliability models
Financial and insurance risk models
Computer and telecommunication networks
Traffic/pedestrian flows
Air traffic safety
Power grids
Climate research
Materials science at low spatial scales
Computational chemistry
Computational biology and genetics
Statistical learning and data analysis

Program and submissions

The program consists of three invited lectures, each lasting 60 minutes, three invited sessions and three contributed sessions. Each speaker in the sessions will have 30 minutes, including questions. Information about plenary speakers, invited and contributed sessions will be updated throughout the summer.

Travel information

Extensive information about getting to Stockholm and KTH can be found here. The following is a brief summary of the

By train

The university campus is situated near the subway (and bus) station Östra Station. When arriving by train to Stockholm Central Station, the subway can be accessed at a lower level (compared to where the train arrives) at the station. Follow the signs and take the red subway line towards "Mörby Centrum", exit at "Tekniska högskolan" (third stop from Stockholm C).

By plane

Via Arlanda Airport (ARN)

From Arlanda Airport take either the express train "Arlanda Express" or commuter rails to Stockholm Central Station. The express train can be accessed from terminals 2 and 5, whereas the commuter rail can be accessed only from Terminal 5 (from "Sky City"). Tickets are available from ticket booths or from the machines, both within the arrival hall (it is not possible to purchase a ticket on either train).

Via Bromma Airport (BMA)

There are both shuttle and local buses going from Bromma Airport to Stockholm Central Station. For the airport shuttle, tickets are sold at the airport Pressbyrån newsagents, at the self-service payment machine at the bus stop, and on board the coach. For local buses, tickets must be purchased in advance; please see SL's webpage for more information, including routes and schedules.
