Query: Preference Incorporation into Many-Objective Optimization: An
  Outranking-based Ant Colony Algorithm   In this paper, we enriched Ant Colony Optimization (ACO) with interval
outranking to develop a novel multiobjective ACO optimizer to approach problems
with many objective functions. This proposal is suitable if the preferences of
the Decision Maker (DM) can be modeled through outranking relations. The
introduced algorithm (named Interval Outranking-based ACO, IO-ACO) is the first
ant-colony optimizer that embeds an outranking model to bear vagueness and
ill-definition of DM preferences. This capacity is the most differentiating
feature of IO-ACO because this issue is highly relevant in practice. IO-ACO
biases the search towards the Region of Interest (RoI), the privileged zone of
the Pareto frontier containing the solutions that better match the DM
preferences. Two widely studied benchmarks were utilized to measure the
efficiency of IO-ACO, i.e., the DTLZ and WFG test suites. Accordingly, IO-ACO
was compared with two competitive many-objective optimizers: The
Indicator-based Many-Objective ACO and the Multiobjective Evolutionary
Algorithm Based on Decomposition. The numerical results show that IO-ACO
approximates the Region of Interest (RoI) better than the leading
metaheuristics based on approximating the Pareto frontier alone.
