PY - 2026 SN - 1052-6234 UR - https://uvadoc.uva.es/handle/10324/83421 AB - We use a vector approach to address, from an efficient point of view, an uncertain unconstrained multiobjective optimization problem with countably many scenarios. Specifically, we introduce several efficient solution notions that work not only in...
