update velocity vkt+1.
Step 9: update velocity using median acceleration factor (in (12)) and generate particles for the next iteration (in (15)) and set k = k + 1.
Nyström & Holmqvist iteratively update velocity thresholds based on the variability of the POR until a convergence criterion (set to 1 deg/s) is reached.
Step 7. Update velocity, position, and inertia weight.

During the process of finding the suboptimal or global solution, the random switchings between two typical operators, namely Operator C and Operator D, which are two different ways to update velocities of all particles, are conducted by a so-called convergence ratio parameter, which can determine the tradeoff between exploration ability and exploitation ability from the quantitative perspective.

z j k and v j k are position and updating velocity of subvector j in iteration k, respectively.
In PSO, the trajectory of each particle is guided by the updated velocity based on gbest and pbest values, therefore a proper balance between them is needed.
Kirchhoff migration of the walkaway VSP, based on the updated velocity model, yielded better fault resolution at the reservoir level than did the surface seismic section.
For DPSO PTS-AIC, updating velocity variables in (8) requires 5 multiplications, 4 additions, and updating location variables requires computing the sigmoid function and generating a random binary variable, per dimension.
