Boundary constraint handling techniques for particle swarm optimization in high dimensional problem spaces

Oldewage, E.T. (Elre); Engelbrecht, Andries P.; Cleghorn, Christopher Wesley (Springer, 2018-10)

This paper investigates the use of boundary constraint handling mechanisms to prevent unwanted particle roaming behaviour in high dimensional spaces. The paper tests a range of strategies on a benchmark for large scale ...
The importance of component-wise stochasticity in particle swarm optimization

Oldewage, E.T. (Elre); Engelbrecht, Andries P.; Cleghorn, Christopher Wesley (Springer, 2018-10)

This paper illustrates the importance of independent, component-wise stochastic scaling values, from both a theoretical and empirical perspective. It is shown that a swarm employing scalar stochasticity is unable to express ...
