Reducing the elastic generalized assignment problem to the standard generalized assignment problem
Büther, Marcel - 2007
The elastic generalized assignment problem (eGAP) is a natural extension of the generalized assignment problem (GAP) where the capacities are not fixed but can be adjusted which is expressed by continuous variables. These variables might be un-bounded or restricted by a lower or upper bound,...
