Query: Surrogate Assisted Evolutionary Algorithm for Medium Scale Expensive
  Multi-Objective Optimisation Problems   Building a surrogate model of an objective function has shown to be effective
to assist evolutionary algorithms (EAs) to solve real-world complex
optimisation problems which involve either computationally expensive numerical
simulations or costly physical experiments. However, their effectiveness mostly
focuses on small-scale problems with less than 10 decision variables. The
scalability of surrogate assisted EAs (SAEAs) have not been well studied yet.
In this paper, we propose a Gaussian process surrogate model assisted EA for
medium-scale expensive multi-objective optimisation problems with up to 50
decision variables. There are three distinctive features of our proposed SAEA.
First, instead of using all decision variables in surrogate model building, we
only use those correlated ones to build the surrogate model for each objective
function. Second, rather than directly optimising the surrogate objective
functions, the original multi-objective optimisation problem is transformed to
a new one based on the surrogate models. Last but not the least, a subset
selection method is developed to choose a couple of promising candidate
solutions for actual objective function evaluations thus to update the training
dataset. The effectiveness of our proposed algorithm is validated on benchmark
problems with 10, 20, 50 variables, comparing with three state-of-the-art
SAEAs.
