Grey Prediction Evolution Algorithm Based on Accelerated Even Grey Model

Abstract: The grey prediction evolution algorithm based on the even grey model (GPEAe) is a pioneer of prediction-based evolutionary algorithms. Its offsprings are generated by a first-order inverse accumulating generation operation (1-IAGO) depending on every prediction of the even grey model. For the fact that the original values are already known for the first few predicted values in 1-IAGO, this paper firstly develops an accelerated 1-IAGO (1-AIAGO) which replaces a particular prediction with the corresponding origi… Show more

“…This issue may cause excess migrations or invalid migrations, resulting in increases in energy consumption and migration costs. To solve this problem, we propose a gray prediction algorithm with residual correction to predict the loads of hosts in the future [19], [42]. The gray prediction algorithm is an exponential prediction model that uses a small amount of incomplete information to establish a mathematical model and make predictions.…”

“…By calculating the fitness function, determine the individual optimal position and the global optimal position of the initial particle swarm (lines 3-9). In the algorithm process, the velocity and position of each particle at each iteration are updated through (35) and (36), a new VM placement plan is generated, and the corresponding fitness function value is calculated (lines [11][12][13][14][15][16][17][18][19][20][21]. For a plan with a fitness value lower than the average value, the placement plan needs to be updated through a mutation operation to ensure the diversity of the placement plan (lines 23-28).…”

“…To further demonstrate the performance of the GPEde on 19 benchmark constrained problems from the CEC 2020, algorithms of DE [7], GPE [20] as well as GPE variant algorithms including GPEAae [47], TOBLGPE [30], GPEAed [27] are selected as comparison algorithms. Table 2 shows the experimental results of GPEde in terms of the four indexes of the worst (Worst), mean (Mean), best (Best) and standard deviation (Std) on the 19 functions.…”

“…To improve the accuracy of grey prediction, the Lagrange mean theorem is used to construct background values, and the initial value is used as a variable to determine the corresponding optimal parameters and time response formula based on the minimum value of the average relative error [15]. In [16], an accelerated first-order inverse accumulation generation method is proposed based on an even number grey prediction model to optimize the propagation operator to improve prediction accuracy. In [17], based on the new information priority principle, fractional order cumulative grey model is used to establish a prediction model, and particle swarm optimization combined with genetic algorithm is applied to determine the optimal order to achieve the prediction of network security forms.…”
