Snarks which do not contain perfect pseudo-matching whose contraction leads to planar/K5-minor-free/SUD-K5-minor-free graphs
In the following we will provide a collection of all snarks with up to 32 vertices that do not contain a planarizing perfect pseudo-matching. For the definition of this property and also the terminology which will be used in the following see [1]. The algorithm used to check the properties is described in [2]. Furthermore, a collection of all snarks with up to 32 vertices provided by the House of Graphs was used.
The following table lists for each snark size (number of vertices) from 26 to 32 the total number of such snarks, the number of snarks which do not have a planarizing perfect pseudo-matching but do have a perfect pseudo-matching whose contraction leads to a K5-minor-free graph [no pppm], the number of snarks which do not have a perfect pseudo matching whose contraction leads to a K5-minor-free graph but have one whose contraction leads to a SUD-K5-minor-free graph [no k5mfppm], and the number of snarks which do not have a perfect pseudo matching whose contraction leads to a SUD-K5-minor-free graph but have one whose contraction leads to a graph containing a compatible circuit decomposition [no sk5mfppm].
You can download the list of all such snarks by pressing on the link of the appropriate cell. The graphs are listed one per line in the graph6 format, see Brendan McKay's website for a formal definition.
Every snark with up to 24 vertices contains a planarizing perfect pseudo-matching. Furthermore, all snarks with up to 32 vertices contain a perfect pseudo-matching whose contraction leads to a graph containinga compatible circuit decomposition.

Balancing Bicycle Sharing System (BBSS) Problem
Contact: Christian Kloimüllner, Petrina Papazek
The homepage of the Balancing Bicylce Sharing System (BBSS) project can be found here.
Our instances are based on real data from Citybike Wien. We got information about 92 stations which contain fill levels at different time in the system, capacity of stations, geographic coordinates, and traveling times between stations.
We constructed instances which contain:
- capacity,
- initial fill level,
- target fill level of stations,
- traveling times, and
- (user) demand values for dynamic rebalancing.
Furthermore, our instances have different size of stations, namely, 10, 20, 30, 60, 90, 120, 180, 240, 300, 400, 500, 600 and 700. Thus, we got a set of artificial stations from our partner, the AIT (Austrian Institute of Technology), which extend the real data we got from Citybike Wien. In particular, we choose the stations for our instances randomly from a set of 92 real stations plus 664 artificial stations.
For the following set of instances we took a snapshot from the system of Citybike Wien to derive initial fill levels for the stations. Furthermore, we set the target value of stations to be 50% of their capacities. We used exactly one depot and also one travel time matrix and the demands for the stations are derived randomly for eight different time points.

In EVOCOP-2013 results we list complete computational results based on bench 2 for comparing our auxilary algroithms for deriving loading operations described in [2013,4].
The next benchmark instances contain (user) demand values for the real stations which we got from our partner, the AIT. For the artificial stations we calculated random demand values according to a Beta distribution.
Moreover, we adopted the initial fill levels and target values. The initial fill levels for the artificial stations have been calculated the same way like we did it for the demands, i.e., such that the distribution of the fill levels for artificial stations is similar to that one of the real stations. The target values were set according to their demand. For stations with a high bike demand we set the target value to be 75% of the stations capacity, for stations with a high slot demand to 25% and if both, the bike- as well as the slot demand, are similar we set their target value to 50% of the capacity.
Additionally, we provided four different travel time matrices which show the traveling time at 4:30 am, 8:00 am, 12:00 pm, as well as 6:15 pm.
