“…Matematicamente, uma variável caótica é aleatória e imprevisível, mas também possui um elemento de regularidade [9]. Em [20] A equação da velocidade para o CPSO com a inclusão do número caótico Cr gerado pelo Mapa Logístico com valor de k=4 em substituição aos números randômicos fica então da seguinte forma:…”

“…The acceleration of the object i, a d i (t), at time t and in the dth direction, is given as Eq. (4): good dynamical behavior [3,24,27,30,50]. In this paper, we use a piecewise linear chaotic map as denoted in (12):…”

“…We abbreviate this chaotic map within range [0,1] as PWL (0, 1). Based on the fact that chaotic search is efficient in a small range of radius defined [24,27,30,50], chaotic local search for a solution can be executed in a small range near current location and global best position, respectively. In this paper, masses take chaotic steps within a dynamically reducing range near the global best of the whole space, as determined by Eqs.…”
