Public transport in the Netherlands

Here is a basic guide to trains, buses and trams in the Netherlands.

The Netherlands has excellent public transport links, and the swipecard payment system OV-chipkaart is the official transport payment system for the metro, bus and tram throughout the Netherlands.

The Nederlandse Spoorwegen (www.ns.nl) is the national train company. Paper train tickets were abolished mid-2014, and infrequent train travellers can buy a single-use chipkaart at 1 EUR extra per trip. The single-use chipcard is a paper ticket with that contains a chip inside. If you are not planning on travelling a great deal, the single-use chipcard is the best option. This paper chipcard can be purchased from an NS ticket machine or a Tickets & Service desk and is valid for all train operators. You do not have to add any credit to this card. When you purchase a single-use chipcard you always pay the full fare, which means you do not get any travel discounts. There is a € 1 supplement on the four most commonly used products (single journey, return ticket, day travel cards and the AnaarBeter ticket) to cover the additional costs of the card.

For the bus and tram there is also the possibility to buy a single-use card. However, that is much more expensive than buying an anonymous OV-chipkaart from an NS ticket machine or a Tickets & Service desk. The OV-chipkaart is the public transport smartcard that is used as a ticket for all public transport in the Netherlands. The same card allows you to travel on the train, tram, bus and metro. You use this card to check in for each mode of transport as you depart and to check out again when you arrive. Your pass can be loaded from one of the OV-chipkaart machines strategically placed at train and metro stations.

If you are planning to travel by bus and train, which is necessary to reach Leiden University, we advise you to buy an anonymous OV-chipkaart from an NS ticket machine or Tickets & Service desk. Before using this card, you have to load your card from one of the OV-chipkaart machines.

Complaints against the Chess programs LOOP and THINKER

David Levy : ICGA President

The ICGA has received formal complaints against the Chess programs LOOP and THINKER, both of which have participated in the World Computer Chess Championship. LOOP was entered by Fritz Reul into the 2007 WCCC in Amsterdam. THINKER was entered into the 2010 WCCC in Kanazawa.

The nature of the complaints is the same in both cases, namely that the programs violated ICGA Tournament Rule 2, which states:

 “Each program must be the original work of the entering developers. Programming teams whose code is derived from or including game-playing code written by others must name all other authors, or the source of such code, in their submission details. Programs which are discovered to be close derivatives of others (e.g., by playing nearly all moves the same), may be declared invalid by the Tournament Director after seeking expert advice. For this purpose a listing of all game-related code running on the system must be available on demand to the Tournament Director.”

As is now well known, the ICGA takes breaches of Rule 2 extremely seriously. In each of these two cases, in the first instances, the ICGA attempted to make contact with the programmers concerned in order to ask for their comments on the allegations against them. In neither case were we successful – emails to their last known email addresses were unanswered, similarly emails sent via known friends and/or colleagues.

The ICGA then asked an independent expert, Mark Watkins, to investigate both programs.  Mark is a member of the Computational Algebra Research Group at the University of Sydney. He had previously carried out comprehensive examinations for the ICGA of the program Rybka and other programs. Mark’s findings are reported on the ICGA investigation wiki at:  http://icga.wikispaces.com/Thinker+Controversy and at http://icga.wikispaces.com/Loop+Controversy

Here we present extracts from the first section of each of Mark Watkins reports.

Loop  “The version examined here is Loop 2007 (64-bit), which was released at approximately the same time as the WCCC. There is notable similarity to Fruit in the evaluation function (other components were not examined).”

Thinker “The versions examined here are Thinker 5.4d Inert (March 2009), and Thinker 5.5.4, entered into Leo Dijksman’s WBEC tournament in January 2011. The first appears to derive from Strelka 2 (thus Rybka 1, and relating to Fruit 2.1). The second appears to derive from IvanHoe (thus partially Rybka 3).”

Based on the above mentioned reports by Mark Watkins the ICGA is convinced that, at the very least, both Fritz Reul and Kerwin Medina have a case to answer. Depending on how Reul and/or Medina respond to these allegations the ICGA might decide to conduct further investigations and/or take some form of strong sanctioning action against the programmers.  However, the ICGA does not intend to proceed further along the route to strong sanctions for the time being, in order to give these programmers more time in which to make contact with the ICGA President and present their defence to the allegations. If either or both of these programmers fail to do so by December 31st 2014, or refuses to do so, the ICGA will disqualify them from all their results in ICGA events.  In the meantime the ICGA has decided to suspend both Fritz Reul and Kerwin Medina from participation in all ICGA events until such time as they have made contact and offered a defence.
