DISCRETE APPLIED MATHEMATICS
Special issue on "Reformulation techniques in mathematical programming"
                        Call for papers

A reformulation of a mathematical programming problem is loosely intended
as a transformation of the problem formulation to an alternative form
which is interesting and/or useful to solve the problem and/or gain
insights about it. As such, "reformulation theory" is extremely
interesting and also very important from a practical point of view.

We would like to invite high-quality submissions for this issue. We
will welcome all contributions focusing on reformulations and/or
relaxations based on the mathematical programming formulation of any
optimization problem form: LP, NLP, IP, MIP, Multi-objective, ...

The guest editors in charge of this fully-refereed special issue will be:

The deadline for submission to 
this issue is tentatively set to 1st december 2006.

The target journal, at the moment, is DAM. Depending on the number of
submitted/accepted contributions, the issue may be published on
Discrete Optimization or Annals of Operations Research.
