Query: A Many-Objective Evolutionary Algorithm with Angle-Based Selection and
  Shift-Based Density Estimation   Evolutionary many-objective optimization has been gaining increasing
attention from the evolutionary computation research community. Much effort has
been devoted to addressing this issue by improving the scalability of
multiobjective evolutionary algorithms, such as Pareto-based,
decomposition-based, and indicator-based approaches. Different from current
work, we propose a novel algorithm in this paper called AnD, which consists of
an angle-based selection strategy and a shift-based density estimation
strategy. These two strategies are employed in the environmental selection to
delete the poor individuals one by one. Specifically, the former is devised to
find a pair of individuals with the minimum vector angle, which means that
these two individuals share the most similar search direction. The latter,
which takes both the diversity and convergence into account, is adopted to
compare these two individuals and to delete the worse one. AnD has a simple
structure, few parameters, and no complicated operators. The performance of AnD
is compared with that of seven state-of-the-art many-objective evolutionary
algorithms on a variety of benchmark test problems with up to 15 objectives.
The experimental results suggest that AnD can achieve highly competitive
performance. In addition, we also verify that AnD can be readily extended to
solve constrained many-objective optimization problems.
