A hybrid patch decomposition approach to compute an enclosure for multi-objective mixed-integer convex optimization problems
Eichfelder, Gabriele; Warnow, Leo - In: Mathematical methods of operations research : ZOR 100 (2024) 1, pp. 291-320
In multi-objective mixed-integer convex optimization, multiple convex objective functions need to be optimized simultaneously while some of the variables are restricted to take integer values. In this paper, we present a new algorithm to compute an enclosure of the nondominated set of such...
