Additional Algorithms for the Generalized Quadratic Assignment Problem (GQAP)

Description
Solutions to the QAP specify the assignment of exactly one facility to exactly one location such that no facility or location remains unassigned.
The Generalized QAP (GQAP) loosens this restriction and instead introduces a capacity at each location and a required capacity for each facility. Multiple facilities can then be assigned to the same location as long as there is enough free capacity.

comment:112 Changed 15 months ago by abeham
The instance map should present the points by giving each algorithm a unique color and thus showing the best algorithm for a certain target. Some tie-breaking should be done in case there are multiple best (e.g. consider the ERT values instead of the ranks).
