Venue

Kapellerput Conference Hotel, Heeze

The hotel is located in a friendly environment, in a small town called Heeze, southwest of Eindhoven. The surrounding woods are great for short walks and relaxing.

Food

The registration fee includes all meals during the conference: breakfast, (dutch) lunch, and a plentiful dinner, as well as refreshments during breaks.

Travel

Getting to Heeze

The best way to get to Heeze is by train from Eindhoven central station. There is a train every 30 minutes, and the travel time is 9 minutes. Transportation will be arranged from Heeze train station to the hotel by the organizers.

Getting to Eindhoven

Eindhoven airport serves mostly cheaper airlines from various European destinations. From the airport, you can get to Eindhoven Central station by bus 10, 400 or 401 in approximately 25 minutes. The second best option is to fly to Amsterdam Schiphol airport: there is a direct InterCity train from Schiphol to Eindhoven. Other nearby options include Dusseldorf and Brussels, as well as the smaller airports in Rotterdam and Maastricht.

Domestic travel in The Netherlands

For travel planning, you can use Google Maps or 9292. We suggest using these planners even for the below routes because the train schedules and optimal routes often change due to construction work.

Airport Min. travel time Route (details on tickets below)
Amsterdam (AMS) 1:30 Train, direct connection to Eindhoven (every 30 min., travel time 1:29)
Eindhoven (EIN) 0:25 Bus 400 or 401 to Eindhoven central station (every 5-10 min., travel time 0:21 to 0:26)
Rotterdam (RTM) 1:30 Bus 33 every 15 min., travel time 0:22 to Rotterdam central station, then train every 30 min. to Eindhoven, (travel time 1:03)
Maastricht (MST) 1:30 Bus 30 to Beek-Elsloo train station (every 30 min, travel time 14 min), then train to Heeze changing twice in Roermond and Weert (travel time 1:12)
Düsseldorf (DUS) 1:40 (bus) Direct IC bus to Eindhoven (once per hour)
Brussels (BRU) 2:30 Train to Eindhoven, changing twice in Roosendaal, and Tilburg (once per hour)

In the Netherlands, paper tickets for single journeys are available from ticket machines at train stations and from the bus driver on buses. Note that there is an extra charge of 0.50 EUR per paper ticket, so if you plan to travel a little more, consider buying an anonymous OV-chipkaart.

Registration

The below registration prices include the conference registration fee, the proceedings, accommodation from June 20 till June 23, meals, some drinks, and the excursion. We have discount prices for students, and there is also an option to have a non-participating partner come along (accommodated in a room shared with the participant).
Note that there is a limited amount of rooms, so it is advisable to register soon.

Call for papers

43rd International Workshop on Graph-Theoretic Concepts in Computer Science

June 21-23, Heeze (near Eindhoven), the Netherlands
Submission Deadline: Feb 27, 2017, 23:59 (Anywhere on Earth)
Notification: April 24, 2017

The WG 2017 conference is the 43rd edition of the WG series. It will take place in hotel Kapellerput in Heeze, near Eindhoven, the Netherlands. The conference will be from Wednesday June 21 to Friday June 23, 2017. Participants are expected to arrive in Heeze on Tuesday June 20, where we will have a welcome reception in the evening.

Aims and Scope

WG conferences aim to connect theory and applications by demonstrating how graph-theoretic concepts can be applied in various areas of computer science. The goal is to present recent results and to identify and explore directions for future research. Submitted papers should describe original results in any aspects of graph theory related to computer science, including but not restricted to:

  • design and analysis of sequential, parallel, randomized, parameterized, and distributed graph and network algorithms,
  • structural graph theory with algorithmic or complexity applications,
  • computational complexity of graph and network problems,
  • graph grammars, graph rewriting systems and graph modeling,
  • graph drawing and layouts,
  • computational geometry,
  • computational biology,
  • random graphs and models of the web and scale-free networks, and
  • support of these concepts by suitable implementations and applications.

Submissions and Proceedings

Contributors are invited to submit an extended abstract of at most 12 pages Springer LNCS format including title, abstract, but excluding references, without changes to the settings of margins and vertical spacing, and with numbered pages. Proofs omitted due to space restrictions must be placed in an appendix, to be read by program committee members at their discretion. Simultaneous submission of papers to any other conference with proceedings published or made publicly available, or submitting papers previously accepted for journal publication is not allowed. Invited papers and accepted contributions will be published in the conference proceedings in the Lecture Notes in Computer Science (LNCS) series of Springer-Verlag.

Best Paper Award and Best Student Paper Award

Thanks to a generous donation by Springer Verlag, WG 2017 is able to offer awards of 500 euro for the best paper and the best student paper. The awards will be decided by the program committee. The committee can decide to split the award(s) over multiple papers. Papers eligible for the best student paper can have non-student co-authors, but the main work in a paper that is a candidate for the best student paper award must be done by co-authors that were students at the time of submission, and the award can be received only by such co-authors. It must be indicated at the time of submission whether a paper is candidate for this award.
