OLD: Only on-site registration possible. Read more

All participants (including speakers) must register for an individual conference or the entire ALGO week at the rates listed below. All prices are given in EUR.

For each paper presented at ALGO, at least one author must be registered for all the days of the respective conference, not just for the day the paper is presented.

During the registration one can register only for one of the six conferences or for the full ALGO. There is no need to register for two parallel conferences, as all scientific and technical events are open for each day one is registered for. The registration of two consecutive conferences would be more expensive than the ALGO registration.

Travel and accommodation are not included in the fee. During the online registration you will be offered to optionally book a reserved room in one of two selected hotels. Still we recommend to carefully compare hotel prices with the standard booking portals. See the accommodation page for more information.

Do you need a visa for Austria? See the visa for Austria page for more information on visas.
