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…
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…
