Workshop on Automated Reasoning
Bridging the Gap between Theory and Practice

 
 
   

Automated Reasoning Workshop 2007

19th-20th April 2007

Department of Computing

Imperial College, London

www.doc.ic.ac.uk/crg/events/ARW07

Continuing the highly successful series of Workshops on Automated Reasoning, this event will provide an informal forum for the automated reasoning community. The ARW workshop series aims to bring together researchers from all areas of automated reasoning in order to foster links and facilitate cross-fertilisation of ideas among researchers from various disciplines; among researchers from academia, industry and government; and between theoreticians and practitioners.

Details of the ARW organisation and of previous ARW events can be found at the ARW website.

TPTP Tea Party

Geoff Sutcliffe will be holding the annual TPTP tea party at Imperial following the ARW workshop. Please see:

Accommodation

Unfortunately, Imperial doesn't rent out its student rooms during the Easter break. However, Imperial does have an accommodation link office, and if you book through them, they can get discounted rates in hotels around the South Kensington area. Having said that, rooms in London are still expensive - sorry about that.

The website to look at is here:

http://www.imperial-accommodationlink.com

The cheapest hotel seems to be Wellington Hotel, which is a little distance away, but not too bad (it is an ex-hall of residence). Their price is 40 pounds per night. The next best is the Norfolk Towers, at 63 pounds per night.

Invited Speakers

Abstract for Geoff's talk:

This talk describes the design, implementation, and testing of a system for selecting necessary axioms from a large set also containing superfluous axioms, to obtain a proof of a conjecture. The selection is determined by semantics of the axioms and conjecture, ordered 40 per night. The next best seems to be The Norfolk Towers, at heuristically by a syntactic relevance measure. The system is able to solve many problems that cannot be solved alone by the underlying automated reasoning system.

Abstract for Alice's talk:

Model checking is an established technique for checking the reliability of software-controlled systems and constitutes one of the leading applications of logic to Computer Science. This automatic technique involves the construction of a model of a system over which properties are checked. One of the major problems with model checking is the (so-called) state-space explosion problem -- where models become too large to feasibly-- -- check. A popular technique for combatting state-space explosion is symmetry reduction. In this talk I introduce a variety of model checkers and give an introduction to symmetry reduction methods, and their implementations.

Presentations

Each workshop attendee will be allocated a 10 minute slot for a short talk to introduce their research. Each attendee will also be allocated space in a poster session, where they can further present and discuss their work. Please prepare posters for the event.

Meals

We have organised lunches for both days of the workshop.

The workshop meal will be in the Med Kitchen, South Kensington.
It is very close to the Department, with a map here:

The restaurant will offer a 3 course menu followed by coffee or tea. Each course features a choice from 4 dishes including a vegetarian option. The cost is 22.95 excluding drinks and gratuity.

Organisers

The workshop is being organised by the Combined Reasoning Group at Imperial.
