The Complexity of Object Association in Multiple Object Tracking

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2021
Object association, i.e., the identification of which observations correspond to the same object, is a central task for the area of multiple object tracking. Two prominent models capturing this task have been introduced in the literature: the Lifted Multicut model and the more recent Lifted Paths model.

A Survey of Solving Approaches for Multiple Objective Flexible Job Shop Scheduling Problems

open access: yesCybernetics and Information Technologies, 2015
Many real life scheduling problems can be formulated as Flexible Job Shop Scheduling Problems (FJSSPs) which simultaneously optimize several conflicting criteria. A typical feature of such problems is their high computational complexity.
