“…To simplify notations, in the following, let = ( − + + )/2 and = ( + − − )/2 for any ∈ 0 and = 0 for any ∈ 1 . For details on how to construct these intervals for missing values, see Li et al [20] and Zhang et al [23].…”

“…Wang et al [22] use an improved backpropagation (BP) neural network to estimate the interval data for missing values. Zhang et al [23] propose an improved interval construction method based on preclassification results and use the particle swarm optimization to search for the optimal clustering. Zhang et al [8] represent the missing values by probabilistic information granules and design an efficient trilevel alternating optimization method to find both the optimal clustering results and the optimal missing values simultaneously.…”

“…If particles relative to the global best position have not improved for consecutive A times, then the particle swarm is considered as gathering to a local optimum location and positions of the entire particle swarm are mutated with a certain mutation probability 1/1(1+t0.5)(1+t0.5), where t stands for the number of iterations. The position of the particle is changed as follows: pjt=r·maxmin+min,where r is a random number uniformly distributed between 0 and 1, and the “max” and the “min” are the upper bound and the lower bound of the search space, respectively …”
