In MO optimization problems, determining the most efficient solution set can be a very daunting process. Many varieties of concepts such as diversity and convergence have been proposed in the past [ 12 ]. These ideas were then used as indicators to evaluate solution sets produced by the optimization algorithm [ 12 ].

Such evaluations were then used to benchmark the algorithm's performance.

These concepts unfortunately could not absolutely state and rank the superiority of solution sets produced by an algorithm against other such sets by other algorithms. Besides, the size of the Pareto frontiers is often directly proportional to the problem size. Since many industrial problems involve continuous functions objectives , the Pareto frontiers obtained are infinite.

Hence, such solutions are computationally impossible. The goal in such scenarios is usually to obtain a good approximation of the Pareto frontier.

The hypervolume indicator HVI [ 13 ] is a set measure reflecting the volume enclosed by a Pareto front approximation and a reference set see [ 14 — 16 ].

The HVI guarantees strict monotonicity regarding Pareto dominance [ 17 , 18 ].

This makes the ranking of solution sets and hence algorithms possible for any given MO problem. Nevertheless, other forms of metrics have also been developed and widely employed for benchmarking solution quality in MO optimization problems such as the convergence metric [ 19 ], diversity metric [ 20 ], and the HVI [ 21 ].

Over the past years, metaheuristic techniques have been applied with increasing frequency to industrial MO optimization problems. Some of the most effective metaheuristic techniques are the ones that spring from evolutionary and swarms approaches.

One such evolutionary approach is the genetic algorithm GA , introduced by Holland in the nineties [ 22 ]. GAs belongs to the group of stochastic search methods such as simulated annealing [ 23 ] and some forms of branch and bound.

While most stochastic search techniques operate on a distinct solution for a particular problem, GAs operates on a population of solutions. In recent times, GAs have been widely applied in industrial scenarios see [ 24 — 26 ]. Differential evolution DE is also a population-based evolutionary algorithm that has been derived from genetic algorithms GA [ 22 ].

DE was developed in the nineties by Storn and Price [ 27 ].

DE has been used extensively to solve problems which are nondifferentiable, noncontinuous, nonlinear, noisy, flat, multidimensional, and having many local minima, constraints, or high degree of stochasticity.

Lately, DE has been applied to a variety of areas including optimization problems in chemical and process engineering [ 28 — 30 ].

## Account Options

One of the most popular swarm-based optimization approaches is the particle swarm optimization PSO algorithm. This optimization method was developed based on the movement and intelligence of swarms. PSO was developed by Kennedy and Eberhart [ 31 ] in Lately, PSO has been applied to a variety of areas including optimization problems in engineering [ 32 ] as well as economic dispatch problems.
