There is a $90 registration fee for this workshop, to be collected onsite. Participants in the DIMACS Challenge do not need to register separately - the ALENEX registration is sufficient. It is necessary to register separately for SODA, and to make your own hotel arrangements. SIAM has extended its room-rate agreement with the Baltimore Omni Hotel to the ALENEX workshop, so be sure to mention ALENEX and/or SODA when you call the hotel.
Attendees who have been offered support should keep two rules in mind. Reimbursement for air travel can only be made for travel on US Flag Carriers, REGARDLESS OF COST. (For example, travel on airlines such as United, Continental, USAir, and others that are United States based are allowable. Travel on airlines such as Lufthansa, SAS, Air Canada and other airlines based outside the US cannot be reimbursed by DIMACS.)
The second rule to keep in mind is to get original receipts for all reimbursable expenses.
