However, in general, the nondominated set may be too large to be enumerated under a tight time budget. In these cases, it is preferable to rapidly obtain a concise representation of the nondominated set that satisfies a given property of interest. This work describes a generic greedy approach to compute a representation of the nondominated set for multiobjective combinatorial optimization problems that approximately maximizes the dominated hypervolume. The representation is built iteratively by solving a sequence of hypervolume scalarized problems, each of which with respect to k reference points, which is a parameter of our approach. We present a mixed-integer formulation of the hypervolume scalarization function for k reference points as well as a combinatorial branch-and-bound for the m-objective knapsack problem. We empirically analyse the functional relationship between k and its running-time and representation quality. Our results indicate that the branch-and-bound is a much more efficient approach and that increasing k does not directly translate into much better representation quality. 2025 0305-0548 https://doi.org/10.1016/j.cor.2025.107140 Computers & Operations Research 183 107140 DAAD-Port2425 https://www.sciencedirect.com/science/article/pii/S0305054825001686 Gonçalo Lopes Kathrin Klamroth Luís Paquete misc abel2025representationintegralkernelcomposition A representation for the integral kernel of the composition of multivariate Bernstein-Durrmeyer operators 2025 https://arxiv.org/abs/2512.17297 Ulrich Abel Ana Maria Acu Margareta Heilmann Ioan Raşa article A Space Mapping approach for the calibration of financial models with the application to the Heston model 2025 10.48550/arXiv.2501.14521 arXiv:2501.14521 A.

In multi-objective optimization, branch and bound algorithms are increasingly attracting interest. However, the larger number of objectives raises additional difficulties for implicit enumeration approaches like branch and bound. Since bounding and pruning is considerably weaker in multiple objectives, many branches have to be (partially) searched and may not be pruned directly. The adaptive use of objective space information can guide the search in promising directions to determine a good approximation of the Pareto front already in early stages of the algorithm. In particular, we focus in this article on improving the branching and queuing of subproblems and the handling of lower bound sets. In our numerical tests, we evaluate the impact of the proposed methods in comparison to a standard implementation of multi-objective branch and bound on knapsack problems, generalized assignment problems and (un)capacitated facility location problems.

These bound sets are used as a supplement to the classical dominance test to improve the computational time by imposing inequalities derived from (partial) dominance in the objective space. This process is called objective branching since it is mostly applied when generating child nodes. In this paper, we extend the concept of objective branching to multi-objective integer optimization problems with three or more objective functions. Several difficulties arise in this case, as there is no longer a lexicographic order among non-dominated outcome vectors when there are three or more objectives. We discuss the general concept of objective branching in any number of dimensions and suggest a merging operation of local upper bounds to avoid the generation of redundant sub-problems. Finally, results from extensive experimental studies on several classes of multi-objective optimization problems is reported. 2022 0305-0548 10.1016/j.cor.2022.106012 Computers & Operations Research 148 148 Multi-objective combinatorial optimization, Multi-objective integer programming, Branch & bound, Objective branching, Bound sets Nicolas Forget Sune Lauth Gadegaard Kathrin Klamroth Lars Relund Nielsen Anthony Przybylski article KONEN2022333 Finding all minimum cost flows and a faster algorithm for the K best flow problem This paper addresses the problem of determining all optimal integer solutions of a linear integer network flow problem, which we call the all optimal integer flow (AOF) problem. We derive an O(F(m+n)+mn+M) time algorithm to determine all F many optimal integer flows in a directed network with n nodes and m arcs, where M is the best time needed to find one minimum cost flow. We remark that stopping Hamacher’s well-known method for the determination of the K best integer flows (Hamacher, 1995) at the first sub-optimal flow results in an algorithm with a running time of O(Fm(nlogn+m)+M) for solving the AOF problem. Our improvement is essentially made possible by replacing the shortest path sub-problem with a more efficient way to determine a so-called proper zero cost cycle using a modified depth-first search technique. As a byproduct, our analysis yields an enhanced algorithm to determine the K best integer flows that runs in O(Kn3+M). Besides, we give lower and upper bounds for the number of all optimal integer and feasible integer solutions. Our bounds are based on the fact that any optimal solution can be obtained by an initial optimal tree solution plus a conical combination of incidence vectors of all induced cycles with bounded coefficients. 2022 0166-218X 10.1016/j.dam.2022.07.007 Discrete Applied Mathematics 321 333-349 Minimum cost flow, K best network flow, Integer network flow algorithm, All optimal solutions, Combinatorial optimization David Könen Daniel Schmidt Christiane Spisla article PAMM_2022 Modeling Minimum Cost Network Flows With Port-Hamiltonian Systems 2022 10.48550/arXiv.2303.13196 PAMM Wiley Onur Tanil Doganay Kathrin Klamroth Bruno Lang Michael Stiglmayr Claudia Totzeck article PHS-pedestrians Multi-scale description of pedestrian collective dynamics with port-Hamiltonian systems 2022 10.48550/arXiv.2211.06503 arXiv:2211.06503 Antoine Tordeux Claudia Totzeck article InfGradCBO Ensemble-based gradient inference for particle methods in optimization and sampling 2022 10.48550/arXiv.2209.15420 arXiv:2209.15420 Claudia Schillings Claudia Totzeck Philipp Wacker article AcuHR2021 Voronovskaya type results for special sequences of operators 2022 10.1007/s13398-021-01157-6 RACSAM 116,19 Ana-Maria Acu Madalina Dancs Margareta Heilmann Ioan Raşa Vlad Paşca article A Bernstein-Schnabl type operator 2022 10.2298/AADM210714011A Applicable Analysis and Discrete Mathematics 16(2) 495-507 Ana-Maria Acu Madalina Dancs Margareta Heilmann Ioan Raşa Vlad Paşca article stiglmayr22decision Decision Space Robustness for Multiobjective Integer Linear Programming 2022 10.1007/s10479-021-04462-w Annals of Operations Research 319 1769--1791 https://www.imacm.uni-wuppertal.de/fileadmin/imacm/preprints/2020/imacm_20_37.pdf Michael Stiglmayr José Rui Figueira Kathrin Klamroth Luís Paquete Britta Schulze article reiners22efficient Efficient and sparse neural networks by pruning weights in a multiobjective learning approach 2022 10.1016/j.cor.2021.105676 Computers & Operations Research 141 105676 Malena Reiners Kathrin Klamroth Fabian Heldmann Michael Stiglmayr article bolten22tracing Tracing locally Pareto optimal points by numerical integration 2022 10.1137/20M1341106 SIAM Journal on Control and Optimization 59 3302-3328 5 Matthias Bolten Onur Tanil Doganay Hanno Gottschalk Kathrin Klamroth article halffmann22MOILPsurvey Exact algorithms for multiobjective linear optimization problems with integer variables - a state of the art survey 2022 10.1002/mcda.1780 Journal of Multicriteria Decision Analysis 29 343–363 Pascal Halffmann Luca E.
