Convex cones, assessment functions, balanced attributes
Ignacy Kaliszewski
We investigate a class of polyhedral convex cones, with (the nonegative orthant in ) as a special case. We start with the observation that for convex cones co…
Bi-Level Optimization to Enhance Intensity Modulated Radiation Therapy Planning
Juan José Moreno, Savíns Puertas-Martín, Juana L. Redondo +7
Intensity Modulated Radiation Therapy is an effective cancer treatment. Models based on the Generalized Equivalent Uniform Dose (gEUD) provide radiation plans with excellent planni…
Approximate solutions to the multiple-choice knapsack problem by multiobjectivization and Chebyshev scalarization
E. M. Bednarczuk, I. Kaliszewski, J. Miroforidis
The method BISSA, proposed by Bednarczuk, Miroforidis, and Pyzel, provides approximate solutions to the multiple-choice knapsack problem. To fathom the optimality gap that is left…
On Upper Approximations of Pareto Fronts
Ignacy Kaliszewski, Janusz Miroforidis
In one of our earlier works, we proposed to approximate Pareto fronts to multiobjective optimization problems by two-sided approximations, one from inside and another from outside…
Pareto suboptimal solutions to large-scale multiobjective multidimensional knapsack problems with assessments of Pareto suboptimality gaps
Ignacy Kaliszewski
When solving large-scale multiobjective optimization problems, solvers can get stuck with the memory or time limit. In such cases, one is left with no information how far is the be…
