These are the problems to solve

The Danish Family Tree 1786 to 1880 – The State Archives (Statens Arkiver)

The State Archives wants a reconstruction of the development of the Danish population from 1786-1880. We have a lot of data from the period, but they are not immediately comparable: Some data is different from other, but apparently cover the same subject, while other data are filed differently, even though they cover the same. For instance can Ane Jensen from Ejby be filed in another set of data as Anne Jensen from Eiby. The State Archives want a solution that sorts and analyzes data, in order to follow social and medical/biological developments in the population.

Social Media Content – Zenbu Social

Zenbu Social would like to develop a ”recipe” for good, commercial content on social media. They want to find out, which combinations of pictures, text, graphics and video that work best in relation to target groups and different businesses by generating the most likes, sharing, comments or just plain sale.

Cut Down on the Salt – AIBAN

AIBAN wishes to be more effective and minimize the manual work, when they calculate the routes for salting roads during the winter. Currently they are spending far too much time calculating routes, amounts of salt and driving time, so AIBAN would like a formula to cut down on the manual work, when making plans for salting.

Do we have a leak? – TREFOR

TREFOR supplies electricity, water and heat for companies and households, and they want a comparison of data from both their own gauges and external ones. That way they will be able to identify whether non-typical data is caused by a leak or perhaps is just the result of meteorological phenomena, for instance.

Is the water clean? – Sulzer

In sewage plants water is cleansed by circulating in large basins were more or less oxygen is added. Sulzer wants a simulation model to show, if the propellers are strong enough to create the needed circulation to penetrate the ”walls” of oxygen, that are pumped into the basin, or if there can be found others, more effective techniques than the combination of circulation and oxidation.

Transparency in procurement procedures – FynBus/SDU, Michael Christensen

FynBus seeks to optimize their procedures for the selection of suppliers in relation to a tender. Thus, they want to construct an algorithm to help them select the best solutions out of many offers, some of which are overlapping. The algorithm should take into account parameters such as economics, quality and efficiency.

Are 5 gates sufficient? – Peter Schneider-Kamp, SDU

Boolean functions are functions which use input from a number of Boolean inputs to compute a value. These values are either TRUE or FALSE. With the functions AND and XOR it is possible to compute all the possible values of TRUE and FALSE. The question to be answered is, if all the possible values can be computed for 6 input by using a maximum of 5 AND gates. The answer may in principle be answered by checking all functions in a truth table with 6 input, but that will result in approximately 18,5 quintillion functions, thus it will take half a billion years or more to solve. Is it possible to find a method to exclude some functions, so the answer can be computed in one month?
